TIdServerIOHandler.Accept Method

Specifies the IOHandler framework for a thread or fiber connections to a server.

Pascal

function Accept(
    ASocket: TIdSocketHandle; 
    AListenerThread: TIdThread; 
    AYarn: TIdYarn
): TIdIOHandler; virtual;

Parameters

Parameters	Description
ASocket	Socket descriptor representing the client connection for the IOHandler.
AListenerThread	Server Listener thread that has detected the connection request.
AYarn	Scheduler for the thread/fiber.

Returns

TIdIOHandler - THe IOHandler created for the client connection to the server.

Description

Accept is a virtual TIdIOHandler function used to create a TIdIOHandler instance for threaded client connections to a server.

ASocket is the socket descriptor representing the client connection for the IOHandler.

AListenerThread is the Listener thread in the server that has detected the client connection request.

AYarn is the scheduler for the threaded or fiber-based client connection.

Accept is called during execution of the listener thread in a multi-thread server when a new threaded client connection is detected. Accept is used to create the managed TIdIOHandler used to read and write to the client connection during execution of the threaded client.

Accept can return Nil when the connection cannot be accepted or the listenter thread has been stopped.

Accept always returns Nil in TIdServerIOHandler, and must be reimplemented in a descendant class (like TIdServerIOHandlerSocket) that provides access to the protocol stack for the platform hosting the Indy library.
