int explain_ioctl_or_die(int fildes, int request, void *data);
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
This function is intended to be used in a fashion similar to the
int result = explain_ioctl_or_die(fildes, request, data);
fildes The fildes, exactly as to be passed to the ioctl(2) system
request The request, exactly as to be passed to the ioctl(2) system
data The data, exactly as to be passed to the ioctl(2) system call.
This function only returns on success, see ioctl(2) for more
