Detailed Description

Constructor & Destructor Documentation

LogConnectionUDP()

LogConnectionUDP	(	const std::string &	hostname,
		unsigned short	port
	)

Create a new UDP log connection with the hostname (as name or IP) and the port to connect to.

if the hostname can not be resolved, this will throw an exception so dereferencing the result is always safe

                                                                                 : m_socket(m_ioservice)
{
  ip::udp::resolver resolver(m_ioservice);
  ip::udp::resolver::query udpquery(udp::v4(), hostname, std::to_string(port));
 
  m_socket.open(ip::udp::v4());
  m_remoteEndpoint = *resolver.resolve(udpquery);
}
