void explain_ustat_or_die	(	dev_t	dev,
		struct ustat *	data
	)

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

dev	The dev, exactly as to be passed to the ustat(2) system call.
data	The data, exactly as to be passed to the ustat(2) system call.

Returns:

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

 explain_ustat_or_die(dev, data);
