CreateServer

• shared_ptr<Server> CreateServer(const int port = 8888)

Example

This example shows one of the simplest possible networked programs. The order of events is as follows:

1. The server and client are created
2. The client attempts to connect to the server
3. The server receives the request from the client to connect
4. The client receives confirmation that it successfully connected to the server
5. The client sends a chat message
6. The server receives the chat message and disconnects from the client
7. The client receives notification it has been disconnected, and the program ends
