how to do socket polling in kernel?


I want to let my server (a thread in kernel) to polling before it do the "accept" a connection request. That is, I want to make sure there indeed is request in the queue before I do the accept. I don't want my server to 'hang' at the accept function call.

Is there such a polling mechanism (function call even better) in socket in kernel?

I will assume that you are using TCP sockets and are talking about the accept() function that accepts connections. When you say kernel thread do you really mean that you are hacking the kernel? You could always try setting your I/O ot non-blocking on the socket FD, then poll with select.

I'm really doing programming in kernel, a device driver actually.

Therefore I have to create a socket in kernel. And I don't see any 'select' function in 'struct socket'. There's only 'poll', and I don't know how to use it and how to fill in a parameter of its, 'poll_table_struct'.

If you really can help on this issue, I'd really appreciate it. Thank you.
