NAME
       explain_ioctl_or_die - control device and report errors

SYNOPSIS
       #include <libexplain/ioctl.h>
       int explain_ioctl_or_die(int fildes, int request, void *data);

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

       This function is intended to be used in a fashion similar to the following example:
	      int result = explain_ioctl_or_die(fildes, request, data);

       fildes  The fildes, exactly as to be passed to the ioctl(2) system call.

       request The request, exactly as to be passed to the ioctl(2) system call.

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

       Returns:
	       This function only returns on success, see ioctl(2) for more information.  On failure, prints an explanation and exit()s.
