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

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.COPYRIGHT¶
