explain_ioctl_or_die
explain_ioctl_or_die(3) Library Functions Manual explain_ioctl_or_die(3)
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.
SEE ALSO
