How do I receive UDP packets using recvfrom() when it would seem that
recvfrom() is not a thread cancellation point on FreeBSD 6.0?
1) select() or poll() instead, then recvfrom(). UDP packets
are never partial IIRC.
Ah, that's a good idea.
2) Unmask a signal in the thread doing the recvfrom(), then
use pthread_kill() to interrupt it (don't use SA_RESTART
for sa_flags in the signal action).
Not practical unfortunately as who knows how many threads are
concurrently doing recvfrom()'s.
Thanks for the hint. I hadn't thought of using poll.
