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.
