I have successfully set up a CFSocket based server model in the carbon based project that can receive data and echo it back to me.
Is this a TCP server? If so, you should use CFSocket for the listening socket but CFStream for each TCP connection (create the stream pair using CFStreamCreatePairWithSocket). CFStream is your best abstraction for TCP streams. Once you have a stream pair you can write data using CFWriteStreamWrite. This is a direct analogue of the classic BSD write() system call, down to the requirement to handle EINTR (-: If you have a traditional Mac OS handle, you can get the buffer size with GetHandleSize and access the buffer by dereferencing the handle. For example: static CFIndex WriteHandle(CFWriteStreamRef writeStream, Handle h) { CFIndex bytesWritten; bytesWritten = CFWriteStreamWrite( writeStream, *h, GetHandleSize(h) ); return bytesWritten; } [Traditional Mac OS veterans will tell you that you should lock the handle around the CFWriteStreamWrite, make sure it's not purged, and call GetHandleSize first, but none of that should be necessary on OS X.] Share and Enjoy -- Quinn "The Eskimo!" <http://www.apple.com/developer/> Apple Developer Relations, Developer Technical Support, Core OS/Hardware _______________________________________________ Do not post admin requests to the list.
