IStreamSocket Class Reference
[Sockets, Stream Sockets, Interfaces, Protected destructors on abstract base classes]
Detailed Description
This interface adds stream socket specific functionality to the IAsyncSocket interface. As you can see that isn't much. This is the interface that you will interact with to access socket functionality when you write a client or server as this is the interface to the socket connection that you are passed when callback events occur on a connection.Public Types | |
