Hi,

  wait_event_interruptible_timeout(VNICClientWQHead,
                                   <condition>, HZ *
100000);

I want to use this function to sleep my process when
there is no activity. But when some data arrives on
socket this function should wake up. I have declared a
wait queue as VNICClientWQHead. So what will be the
condtion here to wake up the process when data is
available on sockets? I have multiple sockets.

Regards,
Mano
