Fix the damn code then, I'm just a docs committer (in theory). And the code
certainly does seem to do this, check in_pcb.c:
if (first > last) {
/*
* counting down
*/
count = first - last;
do {
if (count-- < 0) { /* completely used? */
/*
* Undo any address bind that may have
* occurred above.
*/
inp->inp_laddr.s_addr = INADDR_ANY;
return (EAGAIN);
}
...
What *should* it return?
