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

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.
