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.

- call.

exits, it does not return.
The explain_tcflush_on_error function always returns the value return
by the wrapped tcflush(3) system call.
