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.
