The file operations will always fail. If you specify FILE_FLAG_OVERLAPPED, then you *must* use overlapped I/O when performing the operations.

No. > If I make the writefile non-overlapped and do a write, is there a > possibility that it will hang the application? How about the read? That is what timeouts are for. Gambit
