We use events and wait for it in lib/daemon-windows.c and lib/fatal-signal.c with a combination of poll_wevent_wait(), SetEvent() and ResetEvent(). What is the workflow that you are interested in? We also use events indirectly through sockets (through poll_fd_wait() ) in lib/stream-fd-windows.c and lib/stream-ssl.c. > > Alin. > > -----Mesaj original----- > De la: Gurucharan Shetty [mailto:shet...@nicira.com] > Trimis: Tuesday, September 9, 2014 11:28 PM > Către: Alin Serdean > Cc: dev@openvswitch.org > Subiect: Re: [ovs-dev] [PATCH v2 4/5] Changes needed to netlink-socket for > MSVC > > On Tue, Jul 29, 2014 at 8:23 AM, Alin Serdean > <aserd...@cloudbasesolutions.com> wrote: >> Add two functions set_sock_pid_in_kernel and portid_next.
