Is there a way to get the socket reference by using CFStreamCreatePairWithSocketToHost()?

Question

I am creating a socket tcp connection using CFStreamCreatePairWithSocketToHost like this to get a write stream (I dont want to ready any data):

Answer 1

CFDataRef socketData = CFWriteStreamCopyProperty(writeStream, kCFStreamPropertySocketNativeHandle);
CFSocketNativeHandle handle;
CFDataGetBytes(socketData, CFRangeMake(0, sizeof(CFSocketNativeHandle)), &handle);
// handle now contains the same thing as CFSocketGetNative(aSocket)
