I am using unix socket poll()

If poll returns 0, it means timeout. But does this guarantee that socket connection is STILL Alive?

If the connection was closed, poll will actually return a value > 0.

It might also have set POLLHUP in fds->revents to indicate that the remote side hung up the connection. Check the man page for poll on your system :

        man poll
0
