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.
