Subject: Userspace - Kernel Space "Connector" test

Hi All,

   I want to use the Connector module (CONFIG_CONNECTOR) for Kernel
space to User space communication.  My kernel version is 2.6.22.
Before using it, I am trying out the example programs in the
Documentation folder. I have cn_test.c built into the kernel (not
loaded as a module) and I have compiled ucon.c.

When I run ucon, the programs hangs at the point it polls the socket.

	while (!need_exit) {

		printf("Entered While\n");	
		pfd.events = POLLIN;
		printf("1\n");
		pfd.revents = 0;
		printf("1.1\n");		
->	      switch (poll(&pfd, 1, -1)) {

The source code is the same as in the kernel/Documentation/Connector folder.

How do I get to know whether it is listening to the same socket as
cn_test is sending message on?

Thanks,
Midhun.
