  • UnmapViewOfFile
  • CloseHandle
When there is already a named file-mapping object, the GetLastError function in the CreateFileMapping function may still return the following error message:
ERROR_SUCCESS

Note In this situation, you expect that the GetLastError function in the CreateFileMapping function will return the following error message:
ERROR_ALREADY_EXISTS
