Clearing FD_RECV and FD_CLOSE from the event flags when processing a
recv() event will prevent the other worker threads associated with that
socket from waking up repeatedly, checking recv_busy, then sleeping
without having done anything, wasting time and potentially preventing
them from servicing their other sockets.
- IDirectPlay8Peer::EnumHosts() requires a device address to specify
the service provider to emulate.
- IDirectPlay8Peer::EnumHosts() allows overriding the address/port
that discovery messages are sent to.
- IDirectPlay8Peer::Host() requires at least one address. Addresses
with different service providers are not supported yet.
- Implement IDirectPlay8Peer::GetPeerAddress() method.
- Populate pAddressSender in DPNMSG_ENUM_HOSTS_QUERY message.
- Popupate pAddressPlayer in DPNMSG_INDICATE_CONNECT message.
- Base host addresses created by IDirectPlay8Peer on service provider
of device address given to Host() method.
The threading model used for processing messages here will need
redesigning; we can't allow the application to block the event loop
when processing a message in case it calls something which won't
return until a message is processed.
Final model will probably use a pool of workers which will handle I/O
one-at-a-time, blocking and allowing other threads to deal with the
I/O when in the application message callback.
