explain_ioctl_or_die — control device and report errors
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 following example:
int result = explain_ioctl_or_die(fildes, request, data);
The fildes, exactly as to be passed to the ioctl(2) system call.
The request, exactly as to be passed to the ioctl(2) system call.
The data, exactly as to be passed to the ioctl(2) system call.
This function only returns on success, see ioctl(2) for more information. On failure, prints an explanation and exit()s.
explain ioctl(2) errors
terminate the calling process
