explain_ioctl_or_die − control device and report errors
#include <libexplain/ioctl.h>
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 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.
