int explain_tcflush_on_error(int fildes, int selector);
DESCRIPTION
The explain_tcflush_or_die function is used to call the tcflush(3)
system call. On failure an explanation will be printed to stderr,
obtained from the explain_tcflush(3) function, and then the process
terminates by calling exit(EXIT_FAILURE).
The explain_tcflush_on_error function is used to call the tcflush(3)
system call. On failure an explanation will be printed to stderr,
obtained from the explain_tcflush(3) function, but still returns to the
caller.
fildes The fildes, exactly as to be passed to the tcflush(3) system
call.
selector
The selector, exactly as to be passed to the tcflush(3) system
call.
RETURN VALUE
The explain_tcflush_or_die function only returns on success, see
tcflush(3) for more information. On failure, prints an explanation and
exits, it does not return.
The explain_tcflush_on_error function always returns the value return
by the wrapped tcflush(3) system call.
EXAMPLE

similar to the following example:
explain_tcflush_or_die(fildes, selector);
