Stored procedures
Run on the server, this function accepts a request for connecting to an existing socket found on the server. This function is used to create the communication channel between the server socket and the client socket.
This allows you to create a different communication channel for each client computer. Each one of these communication channels can be handled in an independent thread.
  • If the client computer uses a WINDEV application to connect to this socket, this application will have to use SocketConnect.
  • SocketAccept can be used with the SSL sockets.
  • SocketAccept cannot be used with a UDP socket.
WEBDEV - Server code To use the sockets on the server, check "Allow the server sockets" in the "Advanced" tab of the WEBDEV administrator.
Reminder: A socket is a communication resource used by applications to communicate from one computer to another regardless of the type of network.

<Result>: Character string
  • Name of the communication channel to the client socket that requested the connection. This name will be used by all the other Socket functions to specify this communication channel.
  • Empty string ("") if an error occurred. To get more details on the error, use ErrorInfo.
<Socket name>: Character string
Name of the server socket that accepts the connection.
WINDEV Caution: The socket name is case sensitive.
