Macro
Notes
under DR DOS 3.41 and 5.0, attempts to change the subdirectory bit are simply ignored without an error
BUG: Windows for Workgroups returns error code 05h (access denied) instead of error code 02h (file not found) when attempting to get the attributes of a nonexistent file. This causes open() with O_CREAT and fopen() with the “w” mode to fail in Borland C++.
