Function Documentation

int explain_futimesat_on_error	(	int	fildes,
		const char *	pathname,
		const struct timeval *	data
	)

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

Parameters:

fildes	The fildes, exactly as to be passed to the futimesat(2) system call.
pathname	The pathname, exactly as to be passed to the futimesat(2) system call.
data	The data, exactly as to be passed to the futimesat(2) system call.

Returns:

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

Example:

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

 if (explain_futimesat_on_error(fildes, pathname, data) < 0)
 {
     ...cope with error
     ...no need to print error message
 }

void explain_futimesat_or_die	(	int	fildes,
		const char *	pathname,
		const struct timeval *	data
	)

The explain_futimesat_or_die function is used to call the futimesat(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_futimesat(3) function, and then the process terminates by calling exit(EXIT_FAILURE).

Parameters:

fildes	The fildes, exactly as to be passed to the futimesat(2) system call.
pathname	The pathname, exactly as to be passed to the futimesat(2) system call.
data	The data, exactly as to be passed to the futimesat(2) system call.

Returns:

This function only returns on success, see futimesat(2) for more information. On failure, prints an explanation and exits, it does not return.

Example:

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

 explain_futimesat_or_die(fildes, pathname, data);
