+DriverEntry(

+    _In_ PUNICODE_STRING RegistryPath
+)
+/*++
+
+Routine Description:
+    DriverEntry initializes the driver and is the first routine called by the
+    system after the driver is loaded. DriverEntry specifies the other entry
+    points in the function driver, such as EvtDevice and DriverUnload.
+
+Parameters Description:
+
+    DriverObject - represents the instance of the function driver that is loaded
+    into memory. DriverEntry must initialize members of DriverObject before it
+    returns to the caller. DriverObject is allocated by the system before the
+    driver is loaded, and it is released by the system after the system unloads
+    the function driver from memory.
+
+    RegistryPath - represents the driver specific path in the Registry.
+    The function driver can use the path to store driver related data between
+    reboots. The path does not store hardware instance specific data.
+
+Return Value:
+
+    NTSTATUS
