explain_tcflow_or_die(3) Library Functions Manual explain_tcflow_or_die(3) NAME explain_tcflow_or_die - terminal flow control and report errors SYNOPSIS #include <libexplain/tcflow.h> void explain_tcflow_or_die(int fildes, int action); int explain_tcflow_on_error(int fildes, int action); DESCRIPTION The explain_tcflow_or_die function is used to call the tcflow(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_tcflow(3) function, and then the process terminates by calling exit(EXIT_FAILURE). The explain_tcflow_on_error function is used to call the tcflow(3) sys- tem call. On failure an explanation will be printed to stderr, obtained from the explain_tcflow(3) function, but still returns to the caller. fildes The fildes, exactly as to be passed to the tcflow(3) system call. action The action, exactly as to be passed to the tcflow(3) system call. RETURN VALUE The explain_tcflow_or_die function only returns on success, see tcflow(3) for more information. On failure, prints an explanation and exits, it does not return. The explain_tcflow_on_error function always returns the value return by the wrapped tcflow(3) system call.
