Re: Event driven CFStream protocol in 10.1?

I have been fiddling a lot with using
CFSocketCreateConnectedToSocketSignature and from the connect callback
creating read/write stream pairs with client callbacks scheduled in my run
loop. The socket appears to connect and stay open but the stream callbacks
are never called. I just want to know if this is supposed to work on 10.1 (I
am on 10.1.4). If it turns out that this is indeed the case, I would
appreciate some hints about what I could be doing wrong and will post the
code somewhere so it may be analyzed. Thanks in advance for any help! :)

It's supposed to work; the catch is that the stream needs to own the CFSocket (there's exactly one CFSocket per open file descriptor), but you created the CFSocket using CFSocketCreateConnectedToSocketSignature(), so the CFSocket carries your callback instead of the CFStream's internal one.....

You need to either use CFStream or CFSocket, but not both; either approach is quite do-able. To use CFSocket, just add the ReadCallBack to your callbackTypes and change your callback to look for that event - when the event comes in, there's data waiting to be read on the socket. To use CFStream, just don't create the CFSocket. :)
