GetComponentInstanceA5

You can use the GetComponentInstanceA5 function to retrieve the value of the A5 register for a specified connection. Your component sets the A5 register by calling the SetComponentInstanceA5 function, as previously described. The Component Manager then sets the A5 register for your component each time the client requests service on this connection. If your component has been registered globally and you have not set an A5 value, the A5 register is set to 0. In this case you should use your client's A5 value.

FUNCTION GetComponentInstanceA5 
         (aComponentInstance: ComponentInstance): LongInt;

aComponentInstance

The connection for which to retrieve the A5 value. The Component Manager provides a component instance to your component when the connection is opened.

DESCRIPTION

The GetComponentInstanceA5 function returns the value of the A5 register for the connection.
