如何在不同用户下复制目标进程的套接字

I've hit upon a problem with WSADuplicateSocket, which I'm using to duplicate a socket for use by a different process. It works find when both processes are running under the same Windows user, but fails with error code 10022 (WSAEINVAL) when they are running under different users.I've hit upon a problem with WSADuplicateSocket
