NAME datagram_poll - generic datagram poll
SYNOPSIS unsigned int datagram_poll(struct file * file, struct socket * sock, poll_table * wait);
ARGUMENTS file file struct
wait poll table
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.
