[vlc-devel] [PATCH] [RFC] poll: add comment on WSAEventSelect()

[Steve Lhomme]

This line intrigued me a lot. It turns out accept returns an error "Non-socket
handle specified" if this call is not done, even though the FD_ACCEPT flag was
set. I assume we must release the event hook for that socket if we want to use
it.
