chmod

fnint chmod(string filename, int mode)

A wrapper for the POSIX chmod() function. The chmod() function is used to set the permissions of a file system object.

On Windows the file protection mechanism is not at all POSIX-like, and the underlying chmod() function in the C library just sets or clears the FAT-style READONLY attribute. It does not touch any ACL. Software that needs to manage file permissions on Windows exactly should use the Win32 API.

See your C library manual for more details about chmod().

Parameters

`filename`	a pathname in the GLib file name encoding (UTF-8 on Windows)
`mode`	as in chmod()

Returns

0 if the operation succeeded, -1 on error
