Function Documentation

int explain_chmod_on_error	(	const char *	pathname,
		int	mode
	)

The explain_chmod_on_error function is used to call the chmod(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_chmod(3) function.

This function is intended to be used in a fashion similar to the following example:

 if (explain_chmod_on_error(pathname, mode) < 0)
 {
     ...cope with error
     ...no need to print error message
 }

Parameters:

pathname	The pathname, exactly as to be passed to the chmod(2) system call.
mode	The mode, exactly as to be passed to the chmod(2) system call.

Returns:

The value returned by the wrapped chmod(2) system call.
