Hi Guru, You are right probably either use WaitForMultipleObjects or add wrapper functionality for it.

Is it intentional (I haven't followed the work closely, so I am not sure)? If so, can we cast it? > /* Starts a Netlink "dump" operation, by sending 'request' to the > kernel on a @@ -877,7 +1045,11 @@ nl_dump_done(struct nl_dump *dump) > void nl_sock_wait(const struct nl_sock *sock, short int events) { > +#ifdef _WIN32 > + poll_fd_wait(sock->handle, events); poll_fd_wait() can only be used for sockets. So this will not give you the desired behavior. Did you mean to use poll_wevent_wait() instead? (In which case 'events' will be ignored. ) _______________________________________________ dev mailing list dev@openvswitch.org http://openvswitch.org/mailman/listinfo/dev
