(21:10:25) qrstuv: i had assumed that if you turned on headers mode for a udp connection, reading from the data file could never return 0
(21:10:52) qrstuv: because even if your lister was sent a zero-length datagram, you would still read the udp headers for it
(21:11:58) qrstuv: however i think if the listener gets sent a zero-length datagram, devip will not give you the headers, and your read will return zero
(21:12:58) qrstuv: perhaps making your dns server exit
(21:13:24) qrstuv: could someone who understands how bsd sockets work take a look at /usr/inferno/emu/port/devip.c:/^ipread/+/so_recv and tell me if i'm right?
