Detailed Documentation

This class implements an UDP socket.

Construction

DatagramSocketImpl()

Creates an unconnected, unbound datagram socket.

DatagramSocketImpl(IPAddress::Family family)

Creates an unconnected datagram socket.

The socket will be created for the given address family.

DatagramSocketImpl(poco_socket_t sockfd)

Creates a StreamSocketImpl using the given native socket.

Methods

virtual
void
init(int af)

Creates the underlying native socket.

Subclasses must implement this method so that it calls initSocket() with the appropriate arguments.

The default implementation creates a stream socket.
