Function Documentation

int explain_lutimes_on_error	(	const char *	pathname,
		const struct timeval *	data
	)

The explain_lutimes_on_error function is used to call the lutimes(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_lutimes(3) function.

Parameters:

pathname	The pathname, exactly as to be passed to the lutimes(3) system call.
data	The data, exactly as to be passed to the lutimes(3) system call.

Returns:

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

Example:

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

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

		const struct timeval *	data
	)

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