TwclClientConnection.HalCommunicate(THandle) Method

Implements a hardware-dependent code that communicate with the connected remote device.

Namespace: wclConnections
Delphi
protected
 function HalCommunicate(const Event: THandle): Integer; virtual;

Parameters

Event
Type: THandle

The system even object handle (disconnect event).

Return Value

Type: Integer

If the function succeed the return value is wclErrors.WCL_E_SUCCESS. Otherwise the method returns one of the WCL error codes.

Derived classes must override this method to implement a hardware-dependent code that exchanges data with a remote device.

The method executes in a separate thread.

The method implementation must monitor the Event parameter. The Event parameter is set if the Disconnect method was called and the method must terminate communication and exit.

The default implementation simple waits for the Event and exists when the events signaled.
