- * Name      : BOOL ReadFileEx
- * Purpose   : The ReadFileEx function reads data from a file asynchronously.
- *             It is designed solely for asynchronous operation, unlike the
- *             ReadFile function, which is designed for both synchronous and
- *             asynchronous operation. ReadFileEx lets an application perform
- *             other processing during a file read operation.
- *             The ReadFileEx function reports its completion status asynchronously,
- *             calling a specified completion routine when reading is completed
- *             and the calling thread is in an alertable wait state.
- * Parameters: HANDLE       hFile                handle of file to read
- *             LPVOID       lpBuffer             address of buffer
- *             DWORD        nNumberOfBytesToRead number of bytes to read
- *             LPOVERLAPPED lpOverlapped         address of offset
- *             LPOVERLAPPED_COMPLETION_ROUTINE lpCompletionRoutine address of completion routine
- * Variables :
- * Result    : TRUE / FALSE
- * Remark    :
- * Status    : UNTESTED STUB
