OnSocketAllocated is a TNotifyEvent event handler property signalled when the socket handle in the Binding for the IOHandler has been allocated. 

OnSocketAllocated is triggered in the ConnectClient method after the OnBeforeBind event handler has been triggered and following assignment of IPVersion to the corresponding property in Binding. 

OnSocketAllocated is triggered before assigment of values for the IP and Port number for the Binding using BoundIP, BoundPortMin and BoundPortMax, and before calling the Bind method for the socket handle. 

Application must assign a procedure to the event handler to allow responding to the event notification.
