| csPlatformMemoryMappingPosix::csPlatformMemoryMappingPosix | ( | ) | [protected] |
Create a new mapping.

| void csPlatformMemoryMappingPosix::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 csPlatformMemoryMappingPosix::UnmapWindow | ( | PlatformMemoryMapping & | mapping | ) | [protected] |
Unmap a mapping of the file.
