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.
