select() inside the kernel

[Roi Cohen <roi sangate com>]

I'm interested in socket usage inside the kernel.
Specifically, I would like to implement a select() functionality in the
kernel,
i.e.,  one kernel thread pending on a set of sockets should wake up
as soon as one (or more) of the sockets receives a message.
I'd appreciate a sample code and/or guidelines for implementing a select

functionality.

Thanks,
 Roi.
