Completion Port Question

[Shvalb]

Hi.

I need to develop a scalable server that deals with many requests/replies.

My server should get request from clients and send replies, BUT, from time to time I need my server to initiate a request or deliver data to Clients, is this possible with Completion Port, because as far as I understand, I don't hold any kind of data-structure that contains all Sockets - so I can't write to them explicitly....Am I right?

Thanks.

Yes, WSASend() will give you the same type of completion notification that you get from WSARecv().
... because as far as I understand, I don't hold any kind of data-structure that contains all Sockets ...
I don't understand this part. If you need a std::list of all connected clients, then write code that maintains such a list.

MikeAThon: Don't you mean send() and recv()?

[MikeAThon]

No. With an IOCP architecture, you call WSASend() and WSARecv(), not send() and recv().

Mike:

From your answer I understand now that I can keep a list of all sockets that were created for each Client and use WSASend() and WSARecv().

another question, are you familiar with a framework called ProActor ??
it's an ACE mechansim that (as far as I know) implements CompletionPort in a very easy to use way...

Thanks

Sorry, I am not familiar with ACE or ProActor.
