NdisUnmapFile (Compact 2013)

  • Article

3/26/2014

This function releases a virtual address mapping of a file previously set up with NdisMapFile.

Syntax

VOID NdisUnmapFile(
  NDIS_HANDLE FileHandle
);

Parameters

  • FileHandle
    [in] Specifies the handle returned by NdisOpenFile.

Return Value

None.

Remarks

To reduce resource usage, a network adapter driver should always call NdisUnmapFile when it no longer needs exclusive access to the contents of a file that it opened. Such a driver can map and unmap the file as necessary by using alternating calls to NdisMapFile and NdisUnmapFile until it releases the file handle with NdisCloseFile.
