receive_regionT_receive_regionReceiveRegionReceiveRegionreceive_region (Operator)
Name
receive_regionT_receive_regionReceiveRegionReceiveRegionreceive_region — Receive regions over a socket connection.
Signature
Herror T_receive_region(Hobject* Region, const Htuple Socket)
def receive_region(socket: HHandle) -> HObject
Description
receive_regionreceive_regionReceiveRegionReceiveRegionReceiveRegionreceive_region reads a region object that was sent over the
socket connection determined by SocketSocketSocketSocketsocketsocket by another HALCON
process using the operator send_regionsend_regionSendRegionSendRegionSendRegionsend_region. If no regions have
been sent, the HALCON process calling receive_regionreceive_regionReceiveRegionReceiveRegionReceiveRegionreceive_region blocks
until enough data arrives. For a detailed example, see
open_socket_acceptopen_socket_acceptOpenSocketAcceptOpenSocketAcceptOpenSocketAcceptopen_socket_accept.
