+# Using a Render Pipeline to Render Primitives
+
+Render a simple 2D triangle.
+
+## Overview
+
+In [Using Metal to Draw a View’s Contents](https://developer.apple.com/documentation/metal/basic_tasks_and_concepts/using_metal_to_draw_a_view_s_contents), you learned how to set up an `MTKView` object and to change the view's contents using a render pass.
+That sample simply erased the view's contents to a background color.
+This sample shows you how to configure a render pipeline and use it as part of the render pass to draw a simple 2D colored triangle into the view.
+The sample supplies a position and color for each vertex, and the render pipeline uses that data to render the triangle, interpolating color values between the colors specified for the triangle's vertices.
+
+![Simple 2D Triangle Vertices](Documentation/2DTriangleVertices.png)
+
+The Xcode project contains schemes for running the sample on macOS, iOS, and tvOS.
+
+## Understand the Metal Render Pipeline
+
+A *render pipeline* processes drawing commands and writes data into a render pass’s targets.
+ A render pipeline has many stages, some programmed using shaders and others with fixed or configurable behavior.
+This sample focuses on the three main stages of the pipeline: the vertex stage, the rasterization stage, and the fragment stage.
+The vertex stage and fragment stage are programmable, so you write functions for them in Metal Shading Language (MSL).
+The rasterization stage has fixed behavior.
+
+**Figure 1** Main stages of the Metal graphics render pipeline
+![Main Stages of the Metal Graphics Render Pipeline](Documentation/SimplePipeline.png)
+
+Rendering starts with a drawing command, which includes a vertex count and what kind of primitive to render. For example, here's the drawing command from this sample:
+
+``` objective-c
+// Draw the triangle.
+[renderEncoder drawPrimitives:MTLPrimitiveTypeTriangle
+                  vertexStart:0
+                  vertexCount:3];
+```
+
+The vertex stage provides data for each vertex. When enough vertices have been processed, the render pipeline rasterizes the primitive, determining which pixels in the render targets lie within the boundaries of the primitive. The fragment stage determines the values to write into the render targets for those pixels.
+
+In the rest of this sample, you will see how to write the vertex and fragment functions, how to create the render pipeline state object, and finally, how to encode a draw command that uses this pipeline.
+
+## Decide How Data is Processed by Your Custom Render Pipeline
+
+A vertex function generates data for a single vertex and a fragment function generates data for a single fragment, but you decide how they work.
+You configure the stages of the pipeline with a goal in mind, meaning that you know what you want the pipeline to generate and how it generates those results.
+
+Decide what data to pass into your render pipeline and what data is passed to later stages of the pipeline. There are typically three places where you do this:
+
+- The inputs to the pipeline, which are provided by your app and passed to the vertex stage.
+- The outputs of the vertex stage, which is passed to the rasterization stage.
+- The inputs to the fragment stage, which are provided by your app or generated by the rasterization stage.
+
+In this sample, the input data for the pipeline is the position of a vertex and its color. To demonstrate the kind of transformation you typically perform in a vertex function, input coordinates are defined in a custom coordinate space, measured in pixels from the center of the view. These coordinates need to be translated into Metal's coordinate system.
+
+Declare an `AAPLVertex` structure, using SIMD vector types to hold the position and color data.
+To share a single definition for how the structure is laid out in memory, declare the structure in a common header and import it in both the Metal shader and the app.
+
+``` objective-c
+typedef struct
+{
+    vector_float2 position;
+    vector_float4 color;
+} AAPLVertex;
+```
+
+SIMD types are commonplace in Metal Shading Language, and you should also use them in your app using the simd library.
+SIMD types contain multiple channels of a particular data type, so declaring the position as a `vector_float2` means it contains two 32-bit float values (which will hold the x and y coordinates.)
+Colors are stored using a `vector_float4`, so they have four channels – red, green, blue, and alpha.
+
+In the app, the input data is specified using a constant array:
+
+``` objective-c
+static const AAPLVertex triangleVertices[] =
+{
+    // 2D positions,    RGBA colors
+    { {  250,  -250 }, { 1, 0, 0, 1 } },
+    { { -250,  -250 }, { 0, 1, 0, 1 } },
+    { {    0,   250 }, { 0, 0, 1, 1 } },
+};
+```
+
+The vertex stage generates data for a vertex, so it needs to provide a color and a transformed position.
+Declare a `RasterizerData` structure containing a position and a color value, again using SIMD types. 
+
+``` metal
+struct RasterizerData
+{
+    // The [[position]] attribute of this member indicates that this value
+    // is the clip space position of the vertex when this structure is
+    // returned from the vertex function.
+    float4 position [[position]];
+
+    // Since this member does not have a special attribute, the rasterizer
+    // interpolates its value with the values of the other triangle vertices
+    // and then passes the interpolated value to the fragment shader for each
+    // fragment in the triangle.
+    float4 color;
+};
+```
+
+The output position (described in detail below) must be defined as a `vector_float4`. The color is declared as it was in the input data structure.
+
+You need to tell Metal which field in the rasterization data provides position data, because Metal doesn't enforce any particular naming convention for fields in your struct.
+Annotate the `position` field with the `[[position]]` attribute qualifier to declare that this field holds the output position.
+
+The fragment function simply passes the rasterization stage's data to later stages so it doesn't need any additional arguments.
+
+## Declare the Vertex Function
+
+Declare the vertex function, including its input arguments and the data it outputs.
+Much like compute functions were declared using the `kernel` keyword, you declare a vertex function using the `vertex` keyword.
+
+``` metal
+vertex RasterizerData
+vertexShader(uint vertexID [[vertex_id]],
+             constant AAPLVertex *vertices [[buffer(AAPLVertexInputIndexVertices)]],
+             constant vector_uint2 *viewportSizePointer [[buffer(AAPLVertexInputIndexViewportSize)]])
+```
+
+The first argument, `vertexID`, uses the `[[vertex_id]]` attribute qualifier, which is another Metal keyword.
+When you execute a render command, the GPU calls your vertex function multiple times, generating a unique value for each vertex.
+
+The second argument, `vertices`, is an array that contains the vertex data, using the `AAPLVertex` struct previously defined.
+
+To transform the position into Metal's coordinates, the function needs the size of the viewport (in pixels) that the triangle is being drawn into, so this is stored in the `viewportSizePointer` argument.
+
+The second and third arguments have the `[[buffer(n)]]` attribute qualifier.
+By default, Metal assigns slots in the argument table for each parameter automatically.
+When you add the `[[buffer(n)]]` qualifier to a buffer argument, you tell Metal explicitly which slot to use.
+Declaring slots explicitly can make it easier to revise your shaders without also needing to change your app code.
+Declare the constants for the two indicies in the shared header file.
+
+The function's output is a `RasterizerData` struct.
+
+## Write the Vertex Function
+
+Your vertex function must generate both fields of the output struct. 
+Use the `vertexID` argument to index into the `vertices` array and read the input data for the vertex.
+Also, retrieve the viewport dimensions.
+
+``` metal
+float2 pixelSpacePosition = vertices[vertexID].position.xy;
+
+// Get the viewport size and cast to float.
+vector_float2 viewportSize = vector_float2(*viewportSizePointer);
+
+```
+
+Vertex functions must provide position data in *clip-space coordinates*, which are 3D points specified using a four-dimensional homogenous vector (`x,y,z,w`). The rasterization stage takes the output position and divides the `x`,`y`, and `z` coordinates by `w` to generate a 3D point in *normalized device coordinates*. Normalized device coordinates are independent of viewport size.
+
+**Figure 2** Normalized device coordinate system
+![Normalized device coordinate system](Documentation/normalizeddevicecoords.png)
+
+Normalized device coordinates use a *left-handed coordinate system* and map to positions in the viewport.
+Primitives are clipped to a box in this coordinate system and then rasterized.
+The lower-left corner of the clipping box is at an `(x,y)` coordinate of `(-1.0,-1.0)` and the upper-right corner is at `(1.0,1.0)`.
+Positive-z values point away from the camera (into the screen.)
+The visible portion of the `z` coordinate is between `0.0` (the near clipping plane) and `1.0` (the far clipping plane).
+
+Transform the input coordinate system to the normalized device coordinate system.
+
+![Vertex function coordinate transformation](Documentation/metal-coordinate-transformation.png)
+
+Because this is a 2D application and does not need homogenous coordinates, first write a default value to the output coordinate, with the the `w` value is set to `1.0` and the other coordinates set to `0.0`.
+This means that the coordinates are already in the normalized device coordinate space and the vertex function should generate (x,y) coordinates in that coordinate space.
+Divide the input position by half the viewport size to generate normalized device coordinates.
+Since this calculation is performed using SIMD types, both channels can be divided at the same time using a single line of code.
+Perform the divide and put the results in the x and y channels of the output position. 
+
+``` metal
+out.position = vector_float4(0.0, 0.0, 0.0, 1.0);
+out.position.xy = pixelSpacePosition / (viewportSize / 2.0);
+```
+
+Finally, copy the color value into the `out.color` return value.
+
+``` metal
+out.color = vertices[vertexID].color;
+```
+
+## Write a Fragment Function
+
+A *fragment* is a possible change to the render targets. The rasterizer determines which pixels of the render target are covered by the primitive.
+Only fragments whose pixel centers are inside the triangle are rendered.
+
+**Figure 3** Fragments generated by the rasterization stage
+![Fragments generated by the rasterization stage](Documentation/Rasterization.png)
+
+A fragment function processes incoming information from the rasterizer for a single position and calculates output values for each of the render targets. These fragment values are processed by later stages in the pipeline, eventually being written to the render targets.
+
+- Note: The reason a fragment is called a possible change is because the pipeline stages after the fragment stage can be configured to reject some fragments or change what gets written to the render targets. In this sample, all values calculated by the fragment stage are written as-is to the render target.
+
+The fragment shader in this sample receives the same parameters that were declared in the vertex shader's output. Declare the fragment function using the `fragment` keyword. It takes a single argument, the same `RasterizerData` structure that was provided by the vertex stage. Add the `[[stage_in]]` attribute qualifier to indicate that this argument is generated by the rasterizer.
+
+``` metal
+fragment float4 fragmentShader(RasterizerData in [[stage_in]])
+```
+
+If your fragment function writes to multiple render targets, it must declare a struct with fields for each render target.
+Because this sample only has a single render target, you specify a floating-point vector directly as the function's output. This output is the color to be written to the render target.
+
+The rasterization stage calculates values for each fragment's arguments and calls the fragment function with them.
+The rasterization stage calculates its color argument as a blend of the colors at the triangle's vertices.
+The closer a fragment is to a vertex, the more that vertex contributes to the final color.
+
+**Figure 4** Interpolated fragment colors
+![Interpolated Fragment Colors](Documentation/Interpolation.png)
+
+Return the interpolated color as the function's output. 
+
+``` metal
+return in.color;
+```
+
+## Create a Render Pipeline State Object
+
+Now that the functions are complete, you can create a render pipeline that uses them.
+First, get the default library and obtain a [`MTLFunction`][MTLFunction] object for each function.
+
+``` objective-c
+id<MTLLibrary> defaultLibrary = [_device newDefaultLibrary];
+
+id<MTLFunction> vertexFunction = [defaultLibrary newFunctionWithName:@"vertexShader"];
+id<MTLFunction> fragmentFunction = [defaultLibrary newFunctionWithName:@"fragmentShader"];
+```
+
+Next, create a [`MTLRenderPipelineState`][MTLRenderPipelineState] object.
+Render pipelines have more stages to configure, so you use a [`MTLRenderPipelineDescriptor`][MTLRenderPipelineDescriptor] to configure the pipeline.
+
+``` objective-c
+MTLRenderPipelineDescriptor *pipelineStateDescriptor = [[MTLRenderPipelineDescriptor alloc] init];
+pipelineStateDescriptor.label = @"Simple Pipeline";
+pipelineStateDescriptor.vertexFunction = vertexFunction;
+pipelineStateDescriptor.fragmentFunction = fragmentFunction;
+pipelineStateDescriptor.colorAttachments[0].pixelFormat = mtkView.colorPixelFormat;
+
+_pipelineState = [_device newRenderPipelineStateWithDescriptor:pipelineStateDescriptor
+                                                         error:&error];
+```
+
+In addition to specifying the vertex and fragment functions, you also declare the *pixel format* of all render targets that the pipeline will draw into.
+A pixel format ([`MTLPixelFormat`][MTLPixelFormat]) defines the memory layout of pixel data.
+For simple formats, this definition includes the number of bytes per pixel, the number of channels of data stored in a pixel, and the bit layout of those channels.
+Since this sample only has one render target and it is provided by the view, copy the view's pixel format into the render pipeline descriptor.
+Your render pipeline state must use a pixel format that is compatible with the one specified by the render pass.
+In this sample, the render pass and the pipeline state object both use the view's pixel format, so they are always the same.
+
+When Metal creates the render pipeline state object, the pipeline is configured to convert the fragment function's output into the render target's pixel format.
+If you want to target a different pixel format, you need to create a different pipeline state object.
+You can reuse the same shaders in multiple pipelines targeting different pixel formats.
+
+ 
+## Set a Viewport
+
+Now that you have the render pipeline state object for the pipeline, you'll render the triangle. You do this using a render command encoder. First, set the viewport, so that Metal knows which part of the render target you want to draw into.
+
+``` objective-c
+// Set the region of the drawable to draw into.
+[renderEncoder setViewport:(MTLViewport){0.0, 0.0, _viewportSize.x, _viewportSize.y, 0.0, 1.0 }];
+```
+
+## Set the Render Pipeline State
+
+Set the render pipeline state for the pipeline you want to use.
+
+``` objective-c
+[renderEncoder setRenderPipelineState:_pipelineState];
+```
+
+## Send Argument Data to the Vertex Function
+
+Often, you use buffers ([`MTLBuffer`][MTLBuffer]) to pass data to shaders.
+However, when you need to pass only a small amount of data to the vertex function, as is the case here, copy the data directly into the command buffer.
+
+The sample copies data for both parameters into the command buffer.
+The vertex data is copied from an array defined in the sample.
+The viewport data is copied from the same variable that you used to set the viewport. 
+
+In this sample, the fragment function uses only the data it receives from the rasterizer, so there are no arguments to set.
+
+``` objective-c
+[renderEncoder setVertexBytes:triangleVertices
+                       length:sizeof(triangleVertices)
+                      atIndex:AAPLVertexInputIndexVertices];
+
+[renderEncoder setVertexBytes:&_viewportSize
+                       length:sizeof(_viewportSize)
+                      atIndex:AAPLVertexInputIndexViewportSize];
+```
+
+
+## Encode the Drawing Command
+
+Specify the kind of primitive, the starting index, and the number of vertices.
+When the triangle is rendered, the vertex function is called with values of 0, 1, and 2 for the `vertexID` argument.
+
+``` objective-c
+// Draw the triangle.
+[renderEncoder drawPrimitives:MTLPrimitiveTypeTriangle
+                  vertexStart:0
+                  vertexCount:3];
+```
+
+As with Drawing to the Screen Using Metal, you end the encoding process and commit the command buffer.
+However, you could encode more render commands using the same set of steps.
+The final image is rendered as if the commands were processed in the order they were specified.
+(For performance, the GPU is allowed to process commands or even parts of commands in parallel, so long as the final result appears to have been rendered in order. )
+
+## Experiment with the Color Interpolation
+
+In this sample, color values were interpolated across the triangle.
+That's often what you want, but sometimes you want a value to be generated by one vertex and remain constant across the whole primitive.
+Specify the `flat` attribute qualifier on an output of the vertex function to do this.
+Try this now.
+Find the definition of `RasterizerData` in the sample project and add the `[[flat]]` qualifier to its `color` field.
+
+`float4 color [[flat]];`
+
+Run the sample again.
+The render pipeline uses the color value from the first vertex (called the *provoking vertex*) uniformly across the triangle, and it ignores the colors from the other two vertices.
+You can use a mix of flat shaded and interpolated values, simply by adding or omitting the `flat` qualifier on your vertex function's outputs.
+The [Metal Shading Language specification][ShadingLanguageSpec] defines other attribute qualifiers you can also use to modify the rasterization behavior.

Subject: Fix cmake debug flags override

Don't use -DCMAKE_C_FLAGS_DEBUG and -DCMAKE_CXX_FLAGS_DEBUG as this will prevent debug flags generation on Windows (suchs as `/MDd /Zi /Ob0 /Od /RTC1`), use CMAKE_C_FLAGS instead

 ## Introduction ([中文](/README_zh.md))
 
-xmake is a lightweight cross-platform build utility based on Lua. It uses xmake.lua to maintain project builds. Compared with makefile/CMakeLists.txt, the configuration syntax is more concise and intuitive. It is very friendly to novices and can quickly get started in a short time. Let users focus more on actual project development.
+Xmake is a lightweight cross-platform build utility based on Lua.
 
-It can compile the project directly like Make/Ninja, or generate project files like CMake/Meson, and it also has a built-in package management system to help users solve the integrated use of C/C++ dependent libraries.
+It is very lightweight and does not have any dependencies because it has a built-in Lua runtime.

 ## 简介
 
-xmake 是一个基于 Lua 的轻量级跨平台构建工具，使用 xmake.lua 维护项目构建，相比 makefile/CMakeLists.txt，配置语法更加简洁直观，对新手非常友好，短时间内就能快速入门，能够让用户把更多的精力集中在实际的项目开发上。
+Xmake 是一个基于 Lua 的轻量级跨平台构建工具。
 
-虽然，简单易用是 xmake 的一大特色，但 xmake 的功能也是非常强大的，既能够像 Make/Ninja 那样可以直接编译项目，也可以像 CMake/Meson 那样生成工程文件，还有内置的包管理系统来帮助用户解决 C/C++依赖库的集成使用问题。
+它非常的轻量，没有任何依赖，因为它内置了 Lua 运行时。
 
-目前，xmake主要用于 C/C++ 项目的构建，但是同时也支持其他native语言的构建，可以实现跟C/C++进行混合编译，同时编译速度也是非常的快，可以跟Ninja持平。

-    METHOD_NEITHER - in particular and also show how to read & write to file
-    from KernelMode using Zw functions.
-
-    For a non-framework version of sample on how to handle IOCTLs in driver,
-    study src\general\IOCTL in the DDK.
-
-Environment:
-
-    Kernel mode only.

-Module Name:
-
-    testapp.c
-
-Abstract:
-
-    Purpose of this app to test the NONPNP sample driver. The app
-    makes four different ioctl calls to test all the buffer types, write
-    some random buffer content to a file created by the driver in \SystemRoot\Temp
-    directory, and reads the same file and matches the content.
-    If -l option is specified, it does the write and read operation in a loop
-    until the app is terminated by pressing ^C.
-
-    Make sure you have the \SystemRoot\Temp directory exists before you run the test.
-
-Environment:
-
-    Win32 console application.

-Routine Description:
-
-    This routine will get the configuration information and put
-    it and the translated values into CONFIG_DATA structures.
-
-Arguments:
-
-    Device - Handle to a framework device object.
-
-    Resources - Handle to a collection of framework resource objects.
-                This collection identifies the raw (bus-relative) hardware
-                resources that have been assigned to the device.
-
-    ResourcesTranslated - Handle to a collection of framework resource objects.
-                This collection identifies the translated (system-physical)
-                hardware resources that have been assigned to the device.
-                The resources appear from the CPU's point of view.
-                Use this list of resources to map I/O space and
-                device-accessible memory into virtual address space
-
-Return Value:
-
-    STATUS_SUCCESS if consistant configuration was found - otherwise.
-    returns STATUS_SERIAL_NO_DEVICE_INITED.

-
-Routine Description:
-
-    This routine examines several of what might be the serial device
-    registers.  It ensures that the bits that should be zero are zero.
-
-    In addition, this routine will determine if the device supports
-    fifo's.  If it does it will enable the fifo's and turn on a boolean
-    in the extension that indicates the fifo's presence.
-
-    NOTE: If there is indeed a serial port at the address specified
-          it will absolutely have interrupts inhibited upon return
-          from this routine.
-
-    NOTE: Since this routine should be called fairly early in
-          the device driver initialization, the only element
-          that needs to be filled in is the base register address.
-
-    NOTE: These tests all assume that this code is the only
-          code that is looking at these ports or this memory.
-
-          This is a not to unreasonable assumption even on
-          multiprocessor systems.
-
-Arguments:
-
-    Extension - A pointer to a serial device extension.
-    InsertString - String to place in an error log entry.
-    ForceFifo - !0 forces the fifo to be left on if found.
-    LogFifo - !0 forces a log message if fifo found.
-
-Return Value:
-
-    Will return true if the port really exists, otherwise it
-    will return false.

-/*++
-
-Routine Description:
-
-    EvtDeviceD0Entry event callback must perform any operations that are
-    necessary before the specified device is used.  It will be called every
-    time the hardware needs to be (re-)initialized.  This includes after
-    IRP_MN_START_DEVICE, IRP_MN_CANCEL_STOP_DEVICE, IRP_MN_CANCEL_REMOVE_DEVICE,
-    IRP_MN_SET_POWER-D0.
-
-    This function is not marked pageable because this function is in the
-    device power up path. When a function is marked pagable and the code
-    section is paged out, it will generate a page fault which could impact
-    the fast resume behavior because the client driver will have to wait
-    until the system drivers can service this page fault.
-
-    This function runs at PASSIVE_LEVEL, even though it is not paged.  A
-    driver can optionally make this function pageable if DO_POWER_PAGABLE
-    is set.  Even if DO_POWER_PAGABLE isn't set, this function still runs
-    at PASSIVE_LEVEL.  In this case, though, the function absolutely must
-    not do anything that will cause a page fault.
-
-Arguments:
-
-    Device - Handle to a framework device object.
-
-    PreviousState - Device power state which the device was in most recently.
-        If the device is being newly started, this will be
-        PowerDeviceUnspecified.

-
-   This function runs at PASSIVE_LEVEL, though it is generally not paged.  A

-
-   Even if DO_POWER_PAGABLE isn't set, this function still runs at

-// whenever bits 1 through 4 in this register are set.
-//
-
-//
-// This bit is the data ready indicator.  It is set to indicate that

-//
-#define SERIAL_LSR_DR       0x01
-
-//
-// This is the overrun indicator.  It is set to indicate that the receive
-// buffer register was not read befor a new character was transferred
-// into the buffer.  This bit is cleared when this register is read.
-//
-#define SERIAL_LSR_OE       0x02
-
-//
-// This is the parity error indicator.  It is set whenever the hardware
-// detects that the incoming serial data unit does not have the correct
-// parity as defined by the parity select in the line control register.
-// This bit is cleared by reading this register.
-//
-#define SERIAL_LSR_PE       0x04
-
-//
-// This is the framing error indicator.  It is set whenever the hardware
-// detects that the incoming serial data unit does not have a valid

-
-    This function is used to make the head of the particular

-    was the old current request if desired.
-
-Arguments:
-
-    CurrentOpRequest - Pointer to a pointer to the currently active
-                   request for the particular work list.  Note that
-                   this item is not actually part of the list.
-
-    QueueToProcess - The list to pull the new item off of.
-
-    NextIrp - The next Request to process.  Note that CurrentOpRequest

-              cancel spin lock.  However, if *NextIrp is NULL when

-              what is pointed to by CurrentOpRequest will also be NULL.
-              The reason for this is that if the queue is empty
-              when we hold the cancel spin lock, a new request may come
-              in immediately after we release the lock.

-Routine Description:
-
-    This routine is used to process the set mask and wait
-    mask ioctls.  Calls to this routine are serialized by
-    placing irps in the list under the protection of the
-    cancel spin lock.
-
-Arguments:
-
-    Extension - A pointer to the serial device extension.
-
-Return Value:
-
-    Will return pending for everything put the first
-    request that we actually process.  Even in that
-    case it will return pending unless it can complete
-    it right away.

-Routine Description:
-
-    This routine completes the old write as well as getting

-
-    The reason that we have have pointers to the current write

-    read and write.
-
-Arguments:
-
-    CurrentOpRequest - Pointer to the pointer that points to the
-                   current write request.
-
-    QueueToProcess - Pointer to the write queue.
-
-    NewRequest - A pointer to a pointer to the request that will be the
-             current request.  Note that this could end up pointing
-             to a null pointer.  This does NOT necessaryly mean
-             that there is no current write.  What could occur
-             is that while the cancel lock is held the write
-             queue ended up being empty, but as soon as we release

-/*++
-
-Copyright (c) 1990-2000  Microsoft Corporation
-
-Module Name:
-
-    driver.c
-
-Abstract:
-
-    This driver demonstrates use of a default I/O Queue, its
-    request start events, cancellation event, and a synchronized DPC.
-
-    To demonstrate asynchronous operation, the I/O requests are not completed
-    immediately, but stored in the drivers private data structure, and a timer
-    will complete it next time the Timer callback runs.
-
-    During the time the request is waiting for the timer callback to run, it is
-    made cancellable by the call WdfRequestMarkCancelable. This
-    allows the test program to cancel the request and exit instantly.
-
-    This rather complicated set of events is designed to demonstrate
-    the driver frameworks synchronization of access to a device driver
-    data structure, and a pointer which can be a proxy for device hardware
-    registers or resources.
-
-    This common data structure, or resource is accessed by new request
-    events arriving, the Timer callback that completes it, and cancel processing.
-
-    Notice the lack of specific lock/unlock operations.
-
-    Even though this example utilizes a serial queue, a parallel queue
-    would not need any additional explicit synchronization, just a
-    strategy for managing multiple requests outstanding.

-Routine Description:
-
-    This routine is called when a path is removed from a multipath
-    group. The routine will set the path to the appropriate state and
-    fix up the other paths state if they need to change.
-
-    Note: This should NOT be called with DsmContext Lock held
-          This is used for devices supporting ALUA.
-
-Arguements:
-
-    DsmContext is the DSM context
-
-    RemovedDeviceInfo is the device info for the failing/going-away path
-
-    Group is an optional group override.  That is, if Group is not NULL, this
-        function will run the load balance policy on the given Group and not
-        the Group from the RemovedDeviceInfo.  This should only be used when
-        it's impossible to get a pointer to the RemovedDeviceInfo.

-Routine Description:
-
-    This routine is called when an IO that was sent using this path fails with
-    a retry-able "ALUA" error. What this basically means is that most likely an
-    implicit transition has taken place and we need an RTPG to get the updated
-    path states. The routine will send down a Report Target Port Groups command
-    asynchronously to get the paths states (actual work done in the completion
-    routine).
-
-    Note: This should NOT be called with DsmContext Lock held
-          This is used for devices supporting ALUA.
-
-Arguements:
-
-    DsmContext is the DSM context
-
-    FailingDeviceInfo is the device info for the failing/going-away path
-
-    TPGException is a flag used to indicate if the selected path must be from a
-                      TPG that is different from FailingDeviceInfo's. This is
-                      special handling for UA with sense "TPG in SB/UA state"
-
-    DeviceInfoException is a flag used to indicate that the current FailindDeviceInfo
-                      itself needs to be used again. This is special handling for
-                      UA with sense "Asymmetric Access State Changed"
-
-    (NOTE: TPGException and DeviceInfoException are mutually exclusive, although
-           it is okay for both to be FALSE)

-    This routine is builds an entry that contains the alternate devInfo to use for

-Routine Description:
-
-    This routine will handle determine which devices to send the request to based
-    on the service action of the PR-out command.
-    On REGISTER/REGISTER_AND_IGNORE_EXISTING, it will send the command down all
-    paths. If any path succeeds, the PR key will be stored. If failure down any
-    path, return failure.
-    On REGISTER/REGISTER_AND_IGNORE_EXISTING with key == 0 (ie. UNREGISTER),
-    the request is sent down every path. Failure is returned if request fails down
-    any path (but error is ignored if path happens to be one where prior
-    REGISTER/REGISTER_AND_IGNORE_EXISTING had failed in the first place). The
-    stored PR key is cleared irrespective of success/failure being returned.
-    On RESERVE/RELEASE, the command is sent down one path. If it fails, another
-    path is tried. Failure is returned only if none succeed.
-    On CLEAR, command is sent down one path. If it fails, another path is tried.
-    Failure is returned only if none succeed. The stored PR key is cleared
-    irrespective of success/failure being returned.
-    On PREEMPT, command is sent down one path. If it fails, another path is
-    tried. Failure is returned only if none succeed.
-    On PREEMPT_AND_ABORT, command is sent down one path. Failed request is not
-    retried.
-
-    NOTE: If a path shows up later, REGISTER_AND_IGNORE_EXISTING request is
-    built by the IsPathActive routine using the saved PR key and sent down new path.
-
-Arguments:
-
-    DsmContext - DSM context given to MPIO during initialization

-Routine Description:
-
-    This routine will handle determine which devices to send the request to based
-    on the service action of the PR-in command.
-    On READ KEYS, it will send down one path. In case of failure, other paths will
-    be tried until one succeeds. Failure is returned only if it fails down all paths.
-    On READ_RESERVATION/REPORT_CAPABILITIES, command is sent down one path. Failed
-    request is not retried.
-
-Arguments:
-
-    DsmContext - DSM context given to MPIO during initialization
-    DsmIds - The collection of DSM IDs that pertain to the MPDISK.
-    Irp - Irp containing SRB.
-    Srb - Scsi request block
-    Event - The event to
-
-Return Value:
-

-Abstract:
-
-    This driver is the Microsoft Device Specific Module (DSM)
-    devices that conform with SPC-3 specs.
-    It exports behaviors that mpio.sys will use to determine how to
-    multipath these devices.
-
-    This file contains DriverEntry and all the functions that are
-    exported to MPIO.
-
-    This DSM is targetted towards Windows 2008 and above.

-    )
-/*++
-
-Routine Description:
-
-    This routine is used to determine whether the path to DsmId is usable
-    (ie. able to handle requests without a failover).
-
-    Also, after a failover, the path validity will be queried.
-    If the path error was transitory and the DSM feels that the path is good,
-    then this request will be re-issued to determine whether it is usable.
-
-Arguments:
-
-    DsmContext - Context value given to the multipath driver during
-                 registration.
-    PathId - Value set in SetPathId.
-    DsmId - DSM Id returned during DsmInquire.
-
-Return Value:
-
-    TRUE if the path is active. FALSE otherwise.

-    The device that's associated with SuggestedPath will be made active, and the
-    current active device, moved to stand-by.
-
-Arguments:
-
-    DsmContext - Context value given to the multipath driver during registration.
-    DsmIds - The collection of DSM IDs that pertain to the MPDisk.
-    MPIOPath - The original path value passed to SetDeviceInfo.
-    SuggestedPath - The path which should become the active path.
-    Flags - Bitmask indicating the intent of the move.
-
-Return Value:
-
-    NTSTATUS - STATUS_SUCCESS, unless SuggestedPath is somehow invalid.
-               STATUS_INVALID_PARAMETER is ADMIN is set and the path is invalid.

-Routine Description:
-
-    This routine is invoked by MPIO if Status is other than SUCCESS.
-    A few NTSTATUS and SRB_STATUS values indicate a fatal error.
-    Also checked are unit attentions, for which a retry is requested.
-
-Arguments:
-
-    DsmContext - The DSM's context.
-    DsmId - Identifers returned from DMS_INQUIRE_DRIVER.
-    Srb - The Srb with an error.
-    Status - NTSTATUS of the operation. Can be updated.
-    Retry - Allows the DSM to indicate whether to retry the IO.
-    RetryInterval - Lets DSM specify (in seconds) when this specific I/O
-                    should be retried. Use MAXLONG to use the default
-                    retry interval. Use zero to retry immediately.
-
-Return Value:
-
-    DSM_FATAL_ERROR indicates a fatal error.

-    // The requests that will be encountered can be divided into four categories:
-    // 1. The request that has failed.
-    // 2. Subsequent requests that were sent down the failing path that will
-    //    complete with failure.
-    // 3. Requests that were already submitted to LBGetPath() just before InterpretError()
-    //    was called for the failed request (but have yet to have the LB policy
-    //    algo run).
-    // 4. Requests that come into the Dispatch() routine after the failed request
-    //    has been processed by InterpretError().
-    //
-    // For the failed request:
-    // =======================
-    // 1. Find a standby path to make active/optimized.
-    // 2. Send STPG asynchronously as a scsi pass through via IRP_MJ_SCSI (this
-    //    way it can be sent at DISPATCH_IRQL) after setting a completion routine.
-    // 3. Save the devInfo corresponding to the standby path for the failing devInfo.
-    // 4. Return FATAL to MPIO so that new IO are queued.
-    // 5. In the completion routine, update the new states for the devInfos. Then
-    //    clear the saved (previously) standby devInfo for the failing devInfo.
-    //
-    // For the subsequent request that will fail (since it was sent on the failing path):
-    // ==================================================================================
-    // 1. If a standby devInfo has been saved off, it indicates that an STPG was
-    //    already sent, so no need to send another one.
-    // 2. Return FATAL to MPIO so that this request gets queued.
-    //
-    // For the requests that were already submitted to LBGetPath() during this time:
-    // =============================================================================
-    // 1. If there is no active path, check if a standby devInfo has been saved
-    //    away. If it has, return this path. Such requests will fail with check
-    //    condition saying path used is in standby.
-    // 2. In InterpretError() retry (since the error indicates that request
-    //    completed before STPG completed) without decrementing the remaining
-    //    retries count.
-    //
-    // For new requests that come into Dispatch() after above processing:
-    // ==================================================================
-    // We don't need to worry about such requests, since MPIO will queue them
-    // automatically.

-Routine Description:
-
-    Send down request to disable implicit ALUA state transition.
-    The function first sends down a mode sense to get the control extension mode
-    sense data. It then clears the IALUAE bit and sends down a mode select.

-Arguements:
-
-    TargetDevice - Device object that will be target of this command.
-    DisableImplicit - Flag returned to the caller to indicate whether or not
-                      implicit transitions are disabled.
-
-Return Value :
-
-    STATUS_SUCCESS if the command succeeds.
-    Appropriate NTSTATUS code on failure

-Routine Description:
-
-    Copies a reg subtree from source key to destination key.
-    This routine will first copy over all the key's values, and then
-    copy the subkeys, each time recursively handling the subkey's
-    values and its subtree.
-
-Arguments:
-
-    SourceKey - Handle to the root of the subtree to copy over.
-    DestKey   - Handle to the root of the new tree.
-
-Return Value:
-
-    STATUS_SUCCESS upon successfully coping over the tree.
-    Appropriate NT error code in case of failure.

-    calling this function.

-Arguments:
-
-    SpinLock - The EX_SPIN_LOCK to convert from Shared to Exclusive mode.
-
-Return Value:
-
-    Status of the ExTryConvertSharedSpinLockExclusive() call.  This function
-    will always return with the lock acquired in Exclusive mode.  The FALSE is
-    returned, then the lock had to be released and re-acquired.

-Routine Description:
-
-    This routine is called to clear the LUN-specific load balance policy for the given device.
-
-    First, the routine will try to clear the "explicitly set" registry key for the device.  If
-    this fails, the whole routine is aborted.
-
-    If the registry key is successfully cleared, the following happens:
-    1. Check to see if there is a target-wide load balance policy set for this device's VID/PID.
-       If yes, we set the device's load balance policy accordingly and return.
-    2. Check to see if there is an MSDSM-wide load balance policy set.
-       If yes, we set the device's load balance policy accordingly and return.
-    3. If steps 1 and 2 fall through, we set the device's load balance policy to RR, or RRWS if
-       ALUA is enabled.

+Routine Description:
+    Callback invoked when the machine is shutting down.  If you register for
+    a last chance shutdown notification you cannot do the following:
+    o Call any pageable routines
+    o Access pageable memory
+    o Perform any file I/O operations
+
+    If you register for a normal shutdown notification, all of these are
+    available to you.
+
+    This function implementation does nothing, but if you had any outstanding
+    file handles open, this is where you would close them.

+Arguments:
+    Device - The device which registered the notification during init

+Module Name:
+

+
+Abstract:
+
+    Purpose of this app to test the NONPNP sample driver. The app
+    makes four different ioctl calls to test all the buffer types, write
+    some random buffer content to a file created by the driver in \SystemRoot\Temp
+    directory, and reads the same file and matches the content.
+    If -l option is specified, it does the write and read operation in a loop
+    until the app is terminated by pressing ^C.
+
+    Make sure you have the \SystemRoot\Temp directory exists before you run the test.
+
+Environment:
+
+    Win32 console application.

+    It will determine whether the serial port is the source of this

+Return Value:

+Routine Description:
+
+    EvtDeviceReleaseHardware is called by the framework whenever the PnP manager
+    is revoking ownership of our resources.  This may be in response to either
+    IRP_MN_STOP_DEVICE or IRP_MN_REMOVE_DEVICE.  The callback is made before
+    passing down the IRP to the lower driver.
+
+    In this callback, do anything necessary to free those resources.
+    In this driver, we will not receive this callback when there is open handle to
+    the device. We explicitly tell the framework (WdfDeviceSetStaticStopRemove) to
+    fail stop and query-remove when handle is open.
+
+Arguments:
+
+    Device - Handle to a framework device object.
+
+    ResourcesTranslated - Handle to a collection of framework resource objects.
+                This collection identifies the translated (system-physical)

+                The resources appear from the CPU's point of view.

+
+Routine Description:
+
+    This routine examines several of what might be the serial device
+    registers.  It ensures that the bits that should be zero are zero.
+
+    In addition, this routine will determine if the device supports
+    fifo's.  If it does it will enable the fifo's and turn on a boolean
+    in the extension that indicates the fifo's presence.
+
+    NOTE: If there is indeed a serial port at the address specified
+          it will absolutely have interrupts inhibited upon return
+          from this routine.
+
+    NOTE: Since this routine should be called fairly early in
+          the device driver initialization, the only element
+          that needs to be filled in is the base register address.
+
+    NOTE: These tests all assume that this code is the only
+          code that is looking at these ports or this memory.
+
+          This is a not to unreasonable assumption even on
+          multiprocessor systems.
+
+Arguments:
+
+    Extension - A pointer to a serial device extension.
+    InsertString - String to place in an error log entry.
+    ForceFifo - !0 forces the fifo to be left on if found.
+    LogFifo - !0 forces a log message if fifo found.
+
+Return Value:
+
+    Will return true if the port really exists, otherwise it
+    will return false.

+
+Routine Description:
+
+    EvtDeviceD0Entry event callback must perform any operations that are
+    necessary before the specified device is used.  It will be called every
+    time the hardware needs to be (re-)initialized.  This includes after
+    IRP_MN_START_DEVICE, IRP_MN_CANCEL_STOP_DEVICE, IRP_MN_CANCEL_REMOVE_DEVICE,
+    IRP_MN_SET_POWER-D0.
+
+    This function is not marked pageable because this function is in the
+    device power up path. When a function is marked pagable and the code
+    section is paged out, it will generate a page fault which could impact
+    the fast resume behavior because the client driver will have to wait
+    until the system drivers can service this page fault.
+
+    This function runs at PASSIVE_LEVEL, even though it is not paged.  A
+    driver can optionally make this function pageable if DO_POWER_PAGABLE
+    is set.  Even if DO_POWER_PAGABLE isn't set, this function still runs
+    at PASSIVE_LEVEL.  In this case, though, the function absolutely must
+    not do anything that will cause a page fault.

+    request since we don't use a TX buffer.

+

+
+Arguments:
+
+    CurrentOpRequest - Pointer to a pointer to the currently active
+                   request for the particular work list.  Note that
+                   this item is not actually part of the list.
+
+    QueueToProcess - The list to pull the new item off of.
+
+    NextIrp - The next Request to process.  Note that CurrentOpRequest
+              will be set to this value under protection of the
+              cancel spin lock.  However, if *NextIrp is NULL when
+              this routine returns, it is not necessaryly true the
+              what is pointed to by CurrentOpRequest will also be NULL.
+              The reason for this is that if the queue is empty
+              when we hold the cancel spin lock, a new request may come
+              in immediately after we release the lock.
+
+    CompleteCurrent - If TRUE then this routine will complete the

+Routine Description:
+
+    This routine allocates an error log entry, copies the supplied data
+    to it, and requests that it be written to the error log file.
+
+Arguments:
+
+    DriverObject - A pointer to the driver object for the device.
+
+    DeviceObject - A pointer to the device object associated with the
+    device that had the error, early in initialization, one may not
+    yet exist.
+
+    P1,P2 - If phyical addresses for the controller ports involved
+    with the error are available, put them through as dump data.
+
+    SequenceNumber - A ulong value that is unique to an WDFREQUEST over the
+    life of the request in this driver - 0 generally means an error not
+    associated with an request.
+
+    MajorFunctionCode - If there is an error associated with the request,
+    this is the major function code of that request.
+
+    RetryCount - The number of times a particular operation has been
+    retried.
+
+    UniqueErrorValue - A unique long word that identifies the particular
+    call to this function.
+
+    FinalStatus - The final status given to the request that was associated
+    with this error.  If this log entry is being made during one of
+    the retries this value will be STATUS_SUCCESS.
+
+    SpecificIOStatus - The IO status for a particular error.
+
+    LengthOfInsert1 - The length in bytes (including the terminating NULL)
+                      of the first insertion string.
+
+    Insert1 - The first insertion string.
+
+    LengthOfInsert2 - The length in bytes (including the terminating NULL)
+                      of the second insertion string.  NOTE, there must
+                      be a first insertion string for their to be

+
+Copyright (c) 1990-2000  Microsoft Corporation
+
+Module Name:
+
+    driver.c
+
+Abstract:
+
+    This driver demonstrates use of a default I/O Queue, its
+    request start events, cancellation event, and a synchronized DPC.
+
+    To demonstrate asynchronous operation, the I/O requests are not completed
+    immediately, but stored in the drivers private data structure, and a timer
+    will complete it next time the Timer callback runs.
+
+    During the time the request is waiting for the timer callback to run, it is
+    made cancellable by the call WdfRequestMarkCancelable. This
+    allows the test program to cancel the request and exit instantly.
+
+    This rather complicated set of events is designed to demonstrate
+    the driver frameworks synchronization of access to a device driver
+    data structure, and a pointer which can be a proxy for device hardware
+    registers or resources.
+
+    This common data structure, or resource is accessed by new request
+    events arriving, the Timer callback that completes it, and cancel processing.
+
+    Notice the lack of specific lock/unlock operations.
+
+    Even though this example utilizes a serial queue, a parallel queue
+    would not need any additional explicit synchronization, just a
+    strategy for managing multiple requests outstanding.

+     The I/O dispatch callbacks for the frameworks device object
+     are configured in this function.
+
+     A single default I/O Queue is configured for serial request
+     processing, and a driver context memory allocation is created
+     to hold our structure QUEUE_CONTEXT.
+
+     This memory may be used by the driver automatically synchronized
+     by the Queue's presentation lock.
+
+     The lifetime of this memory is tied to the lifetime of the I/O
+     Queue object, and we register an optional destructor callback
+     to release any private allocations, and/or resources.

+                                   tracing.  For example the skeleton uses

+                              initialize the driver's ClassID.     
+

+
+Routine Description:
+
+    This routine is called when an IO that was sent using this path fails with
+    a retry-able "ALUA" error. What this basically means is that most likely an
+    implicit transition has taken place and we need an RTPG to get the updated
+    path states. The routine will send down a Report Target Port Groups command
+    asynchronously to get the paths states (actual work done in the completion
+    routine).
+
+    Note: This should NOT be called with DsmContext Lock held
+          This is used for devices supporting ALUA.
+
+Arguements:
+
+    DsmContext is the DSM context
+
+    FailingDeviceInfo is the device info for the failing/going-away path
+
+    TPGException is a flag used to indicate if the selected path must be from a
+                      TPG that is different from FailingDeviceInfo's. This is
+                      special handling for UA with sense "TPG in SB/UA state"
+
+    DeviceInfoException is a flag used to indicate that the current FailindDeviceInfo
+                      itself needs to be used again. This is special handling for
+                      UA with sense "Asymmetric Access State Changed"
+
+    (NOTE: TPGException and DeviceInfoException are mutually exclusive, although
+           it is okay for both to be FALSE)

+Routine Description:
+
+    This routine will handle determine which devices to send the request to based
+    on the service action of the PR-out command.
+    On REGISTER/REGISTER_AND_IGNORE_EXISTING, it will send the command down all
+    paths. If any path succeeds, the PR key will be stored. If failure down any
+    path, return failure.
+    On REGISTER/REGISTER_AND_IGNORE_EXISTING with key == 0 (ie. UNREGISTER),
+    the request is sent down every path. Failure is returned if request fails down
+    any path (but error is ignored if path happens to be one where prior
+    REGISTER/REGISTER_AND_IGNORE_EXISTING had failed in the first place). The
+    stored PR key is cleared irrespective of success/failure being returned.
+    On RESERVE/RELEASE, the command is sent down one path. If it fails, another
+    path is tried. Failure is returned only if none succeed.
+    On CLEAR, command is sent down one path. If it fails, another path is tried.
+    Failure is returned only if none succeed. The stored PR key is cleared
+    irrespective of success/failure being returned.
+    On PREEMPT, command is sent down one path. If it fails, another path is
+    tried. Failure is returned only if none succeed.
+    On PREEMPT_AND_ABORT, command is sent down one path. Failed request is not
+    retried.
+
+    NOTE: If a path shows up later, REGISTER_AND_IGNORE_EXISTING request is
+    built by the IsPathActive routine using the saved PR key and sent down new path.
+
+Arguments:
+
+    DsmContext - DSM context given to MPIO during initialization

+Routine Description:
+
+    This routine will handle determine which devices to send the request to based
+    on the service action of the PR-in command.
+    On READ KEYS, it will send down one path. In case of failure, other paths will
+    be tried until one succeeds. Failure is returned only if it fails down all paths.
+    On READ_RESERVATION/REPORT_CAPABILITIES, command is sent down one path. Failed
+    request is not retried.
+
+Arguments:
+
+    DsmContext - DSM context given to MPIO during initialization
+    DsmIds - The collection of DSM IDs that pertain to the MPDISK.
+    Irp - Irp containing SRB.
+    Srb - Scsi request block
+    Event - The event to

+Routine Description:
+
+    This routine associates the DsmId to the controlling MPDisk PDO,
+    the targetObject for DSM-initiated requests, and to a Path
+    (given by PathId).
+    This routine will update the PathId in a way that better explains
+    the topology to MPIO.
+    Additionally, if we are in failover LB policy, failback if this
+    path is preferred path.
+    Also, if PR is being used, send registration down this path.
+
+Arguments:
+
+    DsmContext - Context value given to the multipath driver during
+                 registration.
+    TargetObject - The D.O. to which DSM-initiated requests should be sent.
+    DsmId - Value returned from DMSInquireDriver.
+    PathId - Id that represents the path. The value passed in may be used
+             as is, or the DSM optionally can update it if it requires
+             additional state info to be kept.
+
+Return Value:
+
+    INSUFFICENT_RESOURCES for no-mem conditions.

+Routine Description:
+
+    Query the saved load balance policy and preferred path for this device from
+    the registry.
+    Also returns whether this setting was explicitly set via WMI call to SetLBPolicy,
+    (as opposed to the settings being made based on defaults determined through the
+    storage's ALUA capabilities).
+
+Arguements:
+
+    DeviceInfo - The instance of the LUN through a paricular path
+    RegistryKeyName - DeviceName representing this LUN
+    LoadBalanceType - Type of LB policy.
+    PreferredPath - The preferred path for the device.
+    ExplicitlySet - Flag reflecting if LB policy was explicitly set.
+
+Return Value :
+
+    STATUS_SUCCESS if we were able to successfully query the registry for the info.
+
+    Appropriate NTSTATUS code on failure

+Routine Description:
+
+    This routine is called to clear the LUN-specific load balance policy for the given device.
+
+    First, the routine will try to clear the "explicitly set" registry key for the device.  If
+    this fails, the whole routine is aborted.
+
+    If the registry key is successfully cleared, the following happens:
+    1. Check to see if there is a target-wide load balance policy set for this device's VID/PID.
+       If yes, we set the device's load balance policy accordingly and return.
+    2. Check to see if there is an MSDSM-wide load balance policy set.
+       If yes, we set the device's load balance policy accordingly and return.
+    3. If steps 1 and 2 fall through, we set the device's load balance policy to RR, or RRWS if
+       ALUA is enabled.
+
+Arguements:
+
+    DsmContext - Global DSM context
+    DsmIds - DSM Ids for the given device
+
+Return Value:
+

+Module Name:
+
+    ENUM.C
+
+Abstract:
+
+    This source file contains the routines which enumerate the USB bus
+    and populate the TreeView control.
+
+    The enumeration process goes like this:
+
+    (1) Enumerate Host Controllers and Root Hubs
+    EnumerateHostControllers()
+    EnumerateHostController()
+    Host controllers currently have symbolic link names of the form HCDx,
+    where x starts at 0.  Use CreateFile() to open each host controller
+    symbolic link.  Create a node in the TreeView to represent each host
+    controller.
+
+    GetRootHubName()
+    After a host controller has been opened, send the host controller an
+    IOCTL_USB_GET_ROOT_HUB_NAME request to get the symbolic link name of
+    the root hub that is part of the host controller.
+
+    (2) Enumerate Hubs (Root Hubs and External Hubs)
+    EnumerateHub()
+    Given the name of a hub, use CreateFile() to map the hub.  Send the
+    hub an IOCTL_USB_GET_NODE_INFORMATION request to get info about the
+    hub, such as the number of downstream ports.  Create a node in the
+    TreeView to represent each hub.
+
+    (3) Enumerate Downstream Ports
+    EnumerateHubPorts()
+    Given an handle to an open hub and the number of downstream ports on
+    the hub, send the hub an IOCTL_USB_GET_NODE_CONNECTION_INFORMATION_EX
+    request for each downstream port of the hub to get info about the
+    device (if any) attached to each port.  If there is a device attached
+    to a port, send the hub an IOCTL_USB_GET_NODE_CONNECTION_NAME request
+    to get the symbolic link name of the hub attached to the downstream
+    port.  If there is a hub attached to the downstream port, recurse to
+    step (2).  
+    
+    GetAllStringDescriptors()
+    GetConfigDescriptor()
+    Create a node in the TreeView to represent each hub port
+    and attached device.

-Module Name:
-
-    ENUM.C
-
-Abstract:
-
-    This source file contains the routines which enumerate the USB bus
-    and populate the TreeView control.
-
-    The enumeration process goes like this:
-
-    (1) Enumerate Host Controllers and Root Hubs
-    EnumerateHostControllers()
-    EnumerateHostController()
-    Host controllers currently have symbolic link names of the form HCDx,
-    where x starts at 0.  Use CreateFile() to open each host controller
-    symbolic link.  Create a node in the TreeView to represent each host
-    controller.
-
-    GetRootHubName()
-    After a host controller has been opened, send the host controller an
-    IOCTL_USB_GET_ROOT_HUB_NAME request to get the symbolic link name of
-    the root hub that is part of the host controller.
-
-    (2) Enumerate Hubs (Root Hubs and External Hubs)
-    EnumerateHub()
-    Given the name of a hub, use CreateFile() to map the hub.  Send the
-    hub an IOCTL_USB_GET_NODE_INFORMATION request to get info about the
-    hub, such as the number of downstream ports.  Create a node in the
-    TreeView to represent each hub.
-
-    (3) Enumerate Downstream Ports
-    EnumerateHubPorts()
-    Given an handle to an open hub and the number of downstream ports on
-    the hub, send the hub an IOCTL_USB_GET_NODE_CONNECTION_INFORMATION_EX
-    request for each downstream port of the hub to get info about the
-    device (if any) attached to each port.  If there is a device attached
-    to a port, send the hub an IOCTL_USB_GET_NODE_CONNECTION_NAME request
-    to get the symbolic link name of the hub attached to the downstream
-    port.  If there is a hub attached to the downstream port, recurse to
-    step (2).  
-    
-    GetAllStringDescriptors()
-    GetConfigDescriptor()
-    Create a node in the TreeView to represent each hub port
-    and attached device.

Subject: Fix cmake find bug on windows.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

在windows上由于issue 1822 添加了对ImportLibrary的查找，在vcproj里面会有一个与项目同名的lib文件也被加入到link目录。
比如find_package cmake::OpenCV 会导致需要link一个名为OpenCV.lib的文件，但实际上并不存在这一文件，所以需要将其排除。
