	// Initialization and status check
	//

	/// If you know that you are going to be using the relay network (for example,
	/// because you anticipate making P2P connections), call this to initialize the
	/// relay network.  If you do not call this, the initialization will
	/// be delayed until the first time you use a feature that requires access
	/// to the relay network, which will delay that first access.
	///
	/// You can also call this to force a retry if the previous attempt has failed.
	/// Performing any action that requires access to the relay network will also
	/// trigger a retry, and so calling this function is never strictly necessary,
	/// but it can be useful to call it a program launch time, if access to the
	/// relay network is anticipated.
	///
	/// Use GetRelayNetworkStatus or listen for SteamRelayNetworkStatus_t
	/// callbacks to know when initialization has completed.
	/// Typically initialization completes in a few seconds.
	///
	/// Note: dedicated servers hosted in known data centers do *not* need
	/// to call this, since they do not make routing decisions.  However, if
	/// the dedicated server will be using P2P functionality, it will act as
	/// a "client" and this should be called.

	/// ping measurement starts or stops.
	///

	// "Ping location" functions

	// We use the ping times to the valve relays deployed worldwide to
	// generate a "marker" that describes the location of an Internet host.
	// Given two such markers, we can estimate the network latency between
	// two hosts, without sending any packets.  The estimate is based on the
	// optimal route that is found through the Valve network.  If you are
	// using the Valve network to carry the traffic, then this is precisely
	// the ping you want.  If you are not, then the ping time will probably
	// still be a reasonable estimate.
	//
	// This is extremely useful to select peers for matchmaking!
	//
	// The markers can also be converted to a string, so they can be transmitted.
	// We have a separate library you can use on your app's matchmaking/coordinating
	// server to manipulate these objects.  (See steamdatagram_gamecoordinator.h)

	/// age of the data, in seconds, or -1 if no data is available.

	/// It takes a few seconds to initialize access to the relay network.  If
	/// you call this very soon after calling InitRelayNetworkAccess,

	/// be actually used.
	///
	/// If a direct IP route is used (perhaps via NAT traversal), then the route
	/// will be different, and the ping time might be better.  Or it might actually
	/// be a bit worse!  Standard IP routing is frequently suboptimal!
