描述

socket_accept_connectsocket_accept_connectSocketAcceptConnectSocketAcceptConnectSocketAcceptConnectsocket_accept_connect accepts an incoming connection request, generated by open_socket_connectopen_socket_connectOpenSocketConnectOpenSocketConnectOpenSocketConnectopen_socket_connect in another HALCON process or from an external application, on the listening socket AcceptingSocketAcceptingSocketAcceptingSocketAcceptingSocketacceptingSocketaccepting_socket. The listening socket must have been created earlier with open_socket_acceptopen_socket_acceptOpenSocketAcceptOpenSocketAcceptOpenSocketAcceptopen_socket_accept。Its timeout determines the timeout of the socket_accept_connectsocket_accept_connectSocketAcceptConnectSocketAcceptConnectSocketAcceptConnectsocket_accept_connect call. If WaitWaitWaitWaitwaitwait='true'"true""true""true""true""true", socket_accept_connectsocket_accept_connectSocketAcceptConnectSocketAcceptConnectSocketAcceptConnectsocket_accept_connect waits until a connection request from another HALCON process arrives. If WaitWaitWaitWaitwaitwait='false'"false""false""false""false""false", socket_accept_connectsocket_accept_connectSocketAcceptConnectSocketAcceptConnectSocketAcceptConnectsocket_accept_connect returns with the error 5 ( H_MSG_FAIL) , if currently there are no connection requests from other HALCON processes. The value 'auto'"auto""auto""auto""auto""auto" for WaitWaitWaitWaitwaitwait automatically waits if the timeout of the accepting socket is not equal 0. The result of socket_accept_connectsocket_accept_connectSocketAcceptConnectSocketAcceptConnectSocketAcceptConnectsocket_accept_connect is another socket SocketSocketSocketSocketsocketsocket, which is used for a two-way communication with another 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_acceptopen_socket_acceptOpenSocketAcceptOpenSocketAcceptOpenSocketAcceptopen_socket_accept。

For the data transfer with generic sockets only the operators send_datasend_dataSendDataSendDataSendDatasend_data and receive_datareceive_dataReceiveDataReceiveDataReceiveDatareceive_data are available.
