If the fd is a socket then you can also use setsockopt(2) to set SO_RCVTIMEO and check for EWOULDBLOCK (same as EAGAIN) upon read(2) or recv(2) errors. The net effect is the same of using select but the syntax is simpler, IMO. -- If you think things can't get worse it's probably only because you lack sufficient imagination. _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
