explain_tcsendbreak_or_die - send terminal line break and report errors
void explain_tcsendbreak_or_die(int fildes, int duration);
int explain_tcsendbreak_on_error(int fildes, int duration);
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.
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.
The explain_tcsendbreak_or_die function is intended to be used in a fashion similar to the following example:
