send_xldT_send_xldSendXldSendXldsend_xld — Send an XLD object over a socket connection.

Signature

send_xld(XLD : : Socket : )

Herror T_send_xld(const Hobject XLD, const Htuple Socket)

void SendXld(const HObject& XLD, const HTuple& Socket)

static void HOperatorSet.SendXld(HObject XLD, HTuple socket)

void HSocket.SendXld(HXLD XLD)

void HXLD.SendXld(HSocket socket)

def send_xld(xld: HObject, socket: HHandle) -> None

Description

send_xldsend_xldSendXldSendXldsend_xld sends an XLD object over the socket connection determined by SocketSocketSocketsocketsocket. The receiving HALCON process must call receive_xldreceive_xldReceiveXldReceiveXldreceive_xld to read the XLD object from the socket.

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
