Short description🔗

send_xldSendXldSendXldsend_xldT_send_xld — Send an XLD object over a socket connection.

Signature🔗

send_xld( xld XLD, socket Socket )void SendXld( const HObject& XLD, const HTuple& Socket )static void HOperatorSet.SendXld( HObject XLD, HTuple socket )def send_xld( xld: HObject, socket: HHandle ) -> None

Herror T_send_xld( const Hobject XLD, const Htuple Socket )

void HSocket::SendXld( const HXLD& XLD ) const

void HXLD::SendXld( const HSocket& Socket ) const

void HSocket.SendXld( HXLD XLD )

void HXLD.SendXld( HSocket socket )

Description🔗

send_xldSendXld sends an XLD object over the socket connection determined by Socketsocketsocket. The receiving HALCON process must call receive_xldReceiveXld to read the XLD object from the socket.

Execution information🔗

Execution information

  • Multithreading type: reentrant (runs in parallel with non-exclusive operators).

  • Multithreading scope: global (may be called from any thread).

  • Processed without parallelization.

Parameters🔗
