chmod() on an Open File


6.00 6.00a 6.00ax 7.00 | 1.00 1.50 1.51 1.52 MS-DOS | WINDOWS kbprg ------------------------------------------------------------------------- The information in this article applies to: - The C Run-time (CRT), included with: - Microsoft C for MS-DOS, versions 6.0, 6.0a, and 6.0ax - Microsoft C/C++ for MS-DOS, version 7.0 - Microsoft Visual C++ for Windows, versions 1.0, 1.5, 1.51, and 1.52 ------------------------------------------------------------------------- When a file has been opened it is not valid to perform a chmod() on the file. Although some operating systems (for example, UNIX) allow a program to change the permission of a file while it is open, MS-DOS requires the file to be closed before performing this function. Unusual results can occur, particularly when SHARE.EXE is installed, if an attempt is made to chmod() on an open file. One of the results is an error indicating the file is full, when only 1 byte is written to an empty file.
