Detailed Description

Listen on a single socket for incoming connections.

The owner task decides what to do when someone tries to connect.

Constructor & Destructor Documentation

◆ ServerSocket()

ServerSocket::ServerSocket ( const std::string &  label,
Task task,
uint16_t  port,
const std::string &  ip = "127.0.0.1" 
)

Create a new server socket.

Will listen on the given ip address and port number.

Note! If ip is an empty string, the socket will listen on all local IPv4 and IPv6 addresses.
