UnmapViewOfFileEx function (memoryapi.h)
This is an extended version of UnmapViewOfFile that takes an additional flags parameter.
BOOL UnmapViewOfFileEx( [in] PVOID BaseAddress, [in] ULONG UnmapFlags );
A pointer to the base address of the mapped view of a file that is to be unmapped. This value must be identical to the value returned by a previous call to the MapViewOfFile or MapViewOfFileEx function.
This parameter can be one of the following values.
||Specifies that the priority of the pages being unmapped should be temporarily boosted (with automatic short term decay) because the caller expects that these pages will be accessed again shortly from another thread. For more information about memory priorities, see the SetThreadInformation(ThreadMemoryPriority) function.|
||Unmaps a mapped view back to a placeholder (after you've replaced a placeholder with a mapped view using MapViewOfFile2 or MapViewOfFile2FromApp).|
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error information, call GetLastError.
