Member Function Documentation

void csPlatformMemoryMappingWin32::MapWindow	(	PlatformMemoryMapping &	mapping,
		size_t	offset,
		size_t	len
	)			[protected]

Map a part of the file into memory and return a pointer to mapped data.

offset and len are the offset and length of the part of the file to map. Both should be multiples of the granularity returned by GetPageGranularity(); otherwise, the function may fail. Returns 0 in case of failure.

void csPlatformMemoryMappingWin32::UnmapWindow

(

PlatformMemoryMapping &

mapping

)

[protected]

Unmap a mapping of the file.
