DATAGRAM POLL

23       Again totally generic. This also handles sequenced packet sockets
24       providing the socket receive queue is only ever holding data ready to
25       receive.

NOTE

28       when you _don't_ use this routine for this protocol, and you use a
29       different write policy from sock_writeable then please supply your own
30       write_space callback.
