UDP and Datagram Sockets

UDP Socket: udp_socket

UDP sockets can be used for connectionless communications:

sockpp::udp_socket sock;
sockpp::inet_address addr("localhost", 12345);

std::string msg("Hello there!");
sock.send_to(msg, addr);

sockpp::inet_address srcAddr;

char buf[16];
ssize_t n = sock.recv(buf, sizeof(buf), &srcAddr);

See the udpecho.cpp and udpechosvr.cpp examples.
