NdisUnmapFile (Compact 2013)
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.
