socket_accept_connectsocket_accept_connectsocket_accept_connectSocketAcceptConnectSocketAcceptConnect (Operator)

Name

socket_accept_connectsocket_accept_connectsocket_accept_connectSocketAcceptConnectSocketAcceptConnect — Accept a connection request on a listening socket of the protocol type 'HALCON'"HALCON""HALCON""HALCON""HALCON" or 'TCP'"TCP""TCP""TCP""TCP"/'TCP4'"TCP4""TCP4""TCP4""TCP4"/'TCP6'"TCP6""TCP6""TCP6""TCP6".

Signature

Description

socket_accept_connectsocket_accept_connectsocket_accept_connectSocketAcceptConnectSocketAcceptConnect accepts an incoming connection request, generated by open_socket_connectopen_socket_connectopen_socket_connectOpenSocketConnectOpenSocketConnect in another HALCON process or from an external application, on the listening socket AcceptingSocketAcceptingSocketAcceptingSocketAcceptingSocketacceptingSocket. The listening socket must have been created earlier with open_socket_acceptopen_socket_acceptopen_socket_acceptOpenSocketAcceptOpenSocketAccept. Its timeout determines the timeout of the socket_accept_connectsocket_accept_connectsocket_accept_connectSocketAcceptConnectSocketAcceptConnect call. If WaitWaitWaitWaitwait='true'"true""true""true""true", socket_accept_connectsocket_accept_connectsocket_accept_connectSocketAcceptConnectSocketAcceptConnect waits until a connection request from another HALCON process arrives. If WaitWaitWaitWaitwait='false'"false""false""false""false", socket_accept_connectsocket_accept_connectsocket_accept_connectSocketAcceptConnectSocketAcceptConnect returns with the error FAIL, if currently there are no connection requests from other HALCON processes. The value 'auto'"auto""auto""auto""auto" for WaitWaitWaitWaitwait automatically waits if the timeout of the accepting socket is not equal 0. The result of socket_accept_connectsocket_accept_connectsocket_accept_connectSocketAcceptConnectSocketAcceptConnect is another socket SocketSocketSocketSocketsocket, 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_acceptopen_socket_acceptOpenSocketAcceptOpenSocketAccept.

For the data transfer with generic sockets only the operators send_datasend_datasend_dataSendDataSendData and receive_datareceive_datareceive_dataReceiveDataReceiveData are available.

Parallelization

• Multithreading type: reentrant (runs in parallel with non-exclusive operators).
• Multithreading scope: global (may be called from any thread).
• Processed without parallelization.
