Constructor & Destructor Documentation

csPlatformMemoryMappingWin32::csPlatformMemoryMappingWin32 (  )  [protected]

Create a new mapping.

csPlatformMemoryMappingWin32::~csPlatformMemoryMappingWin32 (  )  [protected]

Destroy file mapping.


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.
