DevicePathToDosPath()

static DWORD DevicePathToDosPath ( _In_ LPCWSTR  lpDevicePath, _Out_writes_to_opt_(dwLength, return) LPWSTR  lpDosPath, _In_opt_ DWORD  dwLength  )

static

Maps an NT "\Device\..." path to its Win32 "DOS" equivalent.

Parameters

[in]	lpDevicePath	The NT device path to convert.
[out]	lpDosPath	Receives the converted Win32 path.
[in]	dwLength	Size of the lpDosPath buffer in characters.

Returns

The number of characters required (if lpDosPath == NULL or dwLength == 0), or actually written in the lpDosPath buffer, including the NULL terminator. Returns 0 in case of failure.
