Name

receive_tuplereceive_tuplereceive_tupleReceiveTupleReceiveTuple — Receive a tuple over a socket connection.

Signature

receive_tuple( : : Socket : Tuple)

Herror receive_tuple(const Hlong Socket, char* Tuple)

Herror T_receive_tuple(const Htuple Socket, Htuple* Tuple)

Herror receive_tuple(const HTuple& Socket, char* Tuple)

HTuple HSocket::ReceiveTuple() const

void HOperatorSetX.ReceiveTuple(
[in] VARIANT Socket, [out] VARIANT* Tuple)

VARIANT HSocketX.ReceiveTuple()

static void HOperatorSet.ReceiveTuple(HTuple socket, out HTuple tuple)

HTuple HSocket.ReceiveTuple()

Description

receive_tuplereceive_tuplereceive_tupleReceiveTupleReceiveTuple reads a tuple that was sent over the socket connection determined by SocketSocketSocketSocketsocket by another HALCON process using the operator send_tuplesend_tuplesend_tupleSendTupleSendTuple. If no tuple has been sent, the HALCON process calling receive_tuplereceive_tuplereceive_tupleReceiveTupleReceiveTuple blocks until enough data arrives.
