If no interface is specified in the join it will join on the host's default multicast interface.

Detailed Description

The DtDisSocket class provides an address family independent datagram socket.

Constructor & Destructor Documentation

DtDisSocket::DtDisSocket	(	const DtInetEndpoint &	dest,
		DtU16	localPort = 0,
		DtInetDevice *	hostIf = NULL,
		DtU32	flags = DtDefaultSockOpts,
		bool	immediateOpen = true,
		bool	suppressSelfReflectEnabled = false
	)

DIS Socket Constructor.

Takes a destination endpoint, a source port to use, a pointer to the local network interface device the socket will be bound to, socket option flags, an 'immediateOpen' indicator dictating how the socket should behave upon creation, and a flag to enable self- reflect suppression. If the destination endpoint port is 0 the default DIS port (3000) will be used. The address family (IPv4 or IPv6) is assumed from the destination endpoint object. If suppressSelfReflect is true all packets will be sent from the specified local port or an automatically chosen ephemeral if the localPort parameter is 0. If no host interface is specified the most appropriate interface will be chosen based on the destination. If the destination endpoint specifies a multicast address the multicast group is joined automatically when the socket is opened and the group membership is dropped when the socket is closed. If the 'immediateOpen' parameter is true the socket will immediately try to bind to an interface and allow datagrams to be sent and received. To use custom packet handlers for the send and receive functions the handlers must be set before any call to any of the send and receive methods. To ensure the handlers are configured it is recommended that 'immediateOpen' be set to false so the packet handler callbacks can be configured, then call openSocket(). This ctor will not throw exceptions on failure. Check the socket status by calling state() (or isOk()) to determine if the socket is ready.
