+/// The non-connection-oriented interface to send and receive messages
+/// (whether they be "clients" or "servers").
+///
+/// ISteamNetworkingSockets is connection-oriented (like TCP), meaning you
+/// need to listen and connect, and then you send messages using a connection
+/// handle.  ISteamNetworkingMessages is more like UDP, in that you can just send
+/// messages to arbitrary peers at any time.  The underlying connections are
+/// established implicitly.
+///
+/// Under the hood ISteamNetworkingMessages works on top of the ISteamNetworkingSockets
+/// code, so you get the same routing and messaging efficiency.  The difference is
+/// mainly in your responsibility to explicitly establish a connection and
+/// the type of feedback you get about the state of the connection.  Both
+/// interfaces can do "P2P" communications, and both support both unreliable
+/// and reliable messages, fragmentation and reassembly.
+///
+/// The primary purpose of this interface is to be "like UDP", so that UDP-based code
+/// can be ported easily to take advantage of relayed connections.  If you find
+/// yourself needing more low level information or control, or to be able to better
+/// handle failure, then you probably need to use ISteamNetworkingSockets directly.
+/// Also, note that if your main goal is to obtain a connection between two peers
+/// without concerning yourself with assigning roles of "client" and "server",
+/// you may find the symmetric connection mode of ISteamNetworkingSockets useful.
+/// (See k_ESteamNetworkingConfig_SymmetricConnect.)

+	/// before we can actually begin sending message data.  If this handshaking fails and we can't
+	/// get through, an error will be posted via the callback SteamNetworkingMessagesSessionFailed_t.
+	/// There is no notification when the operation succeeds.  (You should have the peer send a reply
+	/// for this purpose.)

+	/// Sending a message to a host will also implicitly accept any incoming connection from that host.
+	///
+	/// nSendFlags is a bitmask of k_nSteamNetworkingSend_xxx options

+	/// the data on the other end.
+	///
+	/// Using different channels to talk to the same user will still use the same underlying
+	/// connection, saving on resources.  If you don't need this feature, use 0.
+	/// Otherwise, small integers are the most efficient.

+	/// will be be received by the remote host (if they are received at all) exactly once,

+	/// received out of order with respect to each other and with respect to reliable data,

+	/// to be received in the order they were sent.
+	///
+	/// A note for those familiar with TCP/IP ports, or converting an existing codebase that
+	/// opened multiple sockets:  You might notice that there is only one channel, and with
+	/// TCP/IP each endpoint has a port number.  You can think of the channel number as the

+//	steam callback and call-result helpers
+//
+//	The following macros and classes are used to register your application for
+//	callbacks and call-results, which are delivered in a predictable manner.
+//
+//	STEAM_CALLBACK macros are meant for use inside of a C++ class definition.
+//	They map a Steam notification callback directly to a class member function
+//	which is automatically prototyped as "void func( callback_type *pParam )".
+//
+//	CCallResult is used with specific Steam APIs that return "result handles".
+//	The handle can be passed to a CCallResult object's Set function, along with
+//	an object pointer and member-function pointer. The member function will
+//	be executed once the results of the Steam API call are available.
+//
+//	CCallback and CCallbackManual classes can be used instead of STEAM_CALLBACK
+//	macros if you require finer control over registration and unregistration.
+//
+//	Callbacks and call-results are queued automatically and are only
+//	delivered/executed when your application calls SteamAPI_RunCallbacks().
+//
+//  Note that there is an alternative, lower level callback dispatch mechanism.
+//  See SteamAPI_ManualDispatch_Init
+//----------------------------------------------------------------------------------------------------------------------------------------------------------//
+

+//
+// This is safe to call from multiple threads simultaneously,
