receive_xldT_receive_xldReceiveXldReceiveXldreceive_xld — Receive an XLD object over a socket connection.

Signature

receive_xld( : XLD : Socket : )

Herror T_receive_xld(Hobject* XLD, const Htuple Socket)

void ReceiveXld(HObject* XLD, const HTuple& Socket)

HXLD HSocket::ReceiveXld() const

static void HOperatorSet.ReceiveXld(out HObject XLD, HTuple socket)

void HXLD.ReceiveXld(HSocket socket)

def receive_xld(socket: HHandle) -> HObject

Description

receive_xldreceive_xldReceiveXldReceiveXldreceive_xld reads an XLD object that was sent over the socket connection determined by SocketSocketSocketsocketsocket by another HALCON process using the operator send_xldsend_xldSendXldSendXldsend_xld. If no XLD object has been sent, the HALCON process calling receive_xldreceive_xldReceiveXldReceiveXldreceive_xld blocks until enough data arrives. For a detailed example, see send_xldsend_xldSendXldSendXldsend_xld.

Execution Information

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