-Module Name:
-
- dllsup.cpp
-
-Abstract:
-
- This module contains the implementation of the UMDF VirtualSerial Sample
- Driver's entry point and its exported functions for providing COM support.
-
- This module can be copied without modification to a new UMDF driver. It
- depends on some of the code in comsup.cpp & comsup.h to handle DLL
- registration and creating the first class factory.
-
- This module is dependent on the following defines:
-
- MYDRIVER_TRACING_ID - A wide string passed to WPP when initializing
- tracing. For example, VirtualSerial uses
- L"Microsoft\\UMDF\\VirtualSerial"
-
- MYDRIVER_CLASS_ID - A GUID encoded in struct format used to
- initialize the driver's ClassID.
-
- These are defined in internal.h for the sample. If you choose
- to use a different primary include file, you should ensure they are
- defined there as well.
-
-Environment:
-
- WDF User-Mode Driver Framework (WDF:UMDF)

- Routine Description:
-
- This is the entry point and exit point for the I/O trace driver. This
- does very little as the I/O trace driver has minimal global data.

- This method initializes tracing.

- Arguments:
-
- ModuleHandle - the DLL handle for this module.
-
- Reason - the reason this entry point was called.

- Reserved - unused

- Routine Description:
-
- This routine is called by COM in order to instantiate the
- driver callback object and do an initial query interface on it.
-
- This method only creates an instance of the driver's class factory, as this
- is the minimum required to support UMDF.
-
- Arguments:
-
- ClassId - the CLSID of the object being "gotten"
-
- InterfaceId - the interface the caller wants from that object.
-
- Interface - a location to store the referenced interface pointer
-
- Return Value:
-
- S_OK if the function succeeds or error indicating the cause of the
- failure.
