Accept a connection request on a listening socket.
::socket_accept_connect accepts an incoming connection request, generated by ::open_socket_connect in another HALCON process, on the listening socket AcceptingSocket. The listening socket must have been created earlier with ::open_socket_accept. If Wait='true', ::socket_accept_connect waits until a connection request from another HALCON process arrives. If Wait='false', ::socket_accept_connect returns with the error FAIL, if currently there are no connection requests from other HALCON processes. The result of ::socket_accept_connect is another socket Socket, which is used for a two-way communication with another HALCON process. After this connection has been established, data can be exchanged between the two processes by calling the appropriate send or receive operators. For a detailed example, see ::open_socket_accept.
