datagram_poll: generic datagram poll

NAME

datagram_poll - generic datagram poll

SYNOPSIS

unsigned int datagram_poll(struct file * file, struct socket * sock, poll_table * wait);

ARGUMENTS

file

file struct

sock

socket

wait

poll table

DESCRIPTION

Datagram poll: Again totally generic. This also handles sequenced packet sockets providing the socket receive queue is only ever holding data ready to receive.

NOTE

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