c++ - Winsock recv not working after shutdown

Question

I'm trying to get a simple winsock program working, so I create my socket and send my data just fine. Then I use shutdown(ConnectSocket, SD_SEND) which according to msdn, disables sending data, but not receiving? The example on msdn does this too.

But after I call shutdown my recv function returns 0 without receiving any data.
If I comment out the shutdown code, everything works as it should.

Am I missing something?

Answer 1

No, that's normal. The other side responded to your shutdown by shutting down. A zero return from recv indicates a normal connection shutdown. If you don't want the other side to shutdown its half of the connection, don't shut down yours.

(What did you expect the other side to do when its call to recv returned zero?)
