Stored procedures
Run on the server, this function is used to wait for a connection request coming from the client sockets.
Remarks:
  • If the client computer uses a WINDEV application to connect to this socket, the connection request is performed by SocketConnect.
  • UDP-type socket type: The function SocketWaitForConnection function cannot be used with UDP-type sockets.
Reminder A socket is a communication resource used by applications to communicate from one machine to another, regardless of the type of network.
