Hi,Daniel
Thanks for reply, I also try this way before my first post. I use
CFStreamCreatePairWithSocket. but not success.
socket1 = socket(AF_UNIX, SOCK_STREAM, 0);
CFStreamCreatePairWithSocket(kCFAllocatorDefault, socket1,
&reqBodyStream, &reqBodyWriteStream);
CFWriteStreamSetClient(reqBodyWriteStream, kNetworkEvents,
reqBodyReadStreamClientCallBack, &ctxt);
CFWriteStreamScheduleWithRunLoop(reqBodyWriteStream,
CFRunLoopGetCurrent(), kCFRunLoopCommonModes);
Boolean bOpen = CFWriteStreamOpen(reqBodyWriteStream);
there is no kCFSteamEventCanAcceptBytes call back, I don't know why.
I have two questions:
1. why you use socketpair to create a pair of sockets.
2. how can you create CFReadStream or CFWriteStream from the native
socket that created by socketpair.
