I'm using CFStreamCreatePairWithSocketToNetService to get read/write streams. According to the documentation, "The streams do not create a socket, resolve the service, or connect to the service’s host until you open one of the streams." I open the streams with CFReadStreamOpen and CFWriteStreamOpen. The streams are open and can be read from and written to. Yet I can't get the remote host and port from the API. I try CFNetServiceGetTargetHost and CFNetServiceGetPortNumber on both my original CFNetServiceRef and kCFStreamPropertySocketRemoteNetService, but I always get NULL and 0. I try to get kCFStreamPropertySocketRemoteHostName and kCFStreamPropertySocketRemotePortNumber from both the read stream and the write stream, but again I always get NULL. Isn't this supposed to work? Isn't the net service supposed to resolve when you open the streams? _______________________________________________ Do not post admin requests to the list.
