#include <libexplain/tcsendbreak.h>

void explain_tcsendbreak_or_die(int fildes, int duration);
int explain_tcsendbreak_on_error(int fildes, int duration);

Overview

The explain_tcsendbreak_or_die function is used to call the tcsendbreak(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_tcsendbreak(3) function, and then the process terminates by calling exit(EXIT_FAILURE).

The explain_tcsendbreak_on_error function is used to call the tcsendbreak(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_tcsendbreak(3) function, but still returns to the caller.

fildes

The fildes, exactly as to be passed to the tcsendbreak(3) system call.

duration

The duration, exactly as to be passed to the tcsendbreak(3) system call.

Return value

The explain_tcsendbreak_or_die function only returns on success, see tcsendbreak(3) for more information. On failure, prints an explanation and exits, it does not return.

The explain_tcsendbreak_on_error function always returns the value return by the wrapped tcsendbreak(3) system call.

Examples

The explain_tcsendbreak_or_die function is intended to be used in a fashion similar to the following example:

explain_tcsendbreak_or_die(fildes, duration);
