Hi, I'm tracking down an obscure bug in my userland program and it might have something to do with the way I write&read data through a (Unix domain) socket. I'm setting SO_SNDBUF and SO_RCVBUF, and what I'm looking for is some way to query the amount of TX & RX buffered / free data on a socket. Is there something I can use? I'll even accept inspecting kernel structures if explained in detail and can be done on a running system.
Alternatively, is there anything else which could cause poll(2) with POLLOUT on a socket to return no events ready on such a socket? (my expectation being that a socket is always ready to be written to if there is buffer space free...). _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "freebsd-hackers-unsubscr...@freebsd.org"
