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

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.
