DATAGRAM_POLL(9)                         Linux Networking                        DATAGRAM_POLL(9)



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.
