Function Documentation

int explain_futimes_on_error	(	int	fildes,
		const struct timeval *	tv
	)

The explain_futimes_on_error function is used to call the futimes(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_futimes(3) function.

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

 if (explain_futimes_on_error(fildes, tv) < 0)
 {
     ...cope with error
     ...no need to print error message
 }

Parameters:

fildes	The fildes, exactly as to be passed to the futimes(3) system call.
tv	The tv, exactly as to be passed to the futimes(3) system call.

Returns:

The value returned by the wrapped futimes(3) system call.
