                                                                                         explain_ioctl_or_die(3)

       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.
