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 tcsend- break(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) sys- tem 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 re- turn by the wrapped tcsendbreak(3) system call.
