+//	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
+//----------------------------------------------------------------------------------------------------------------------------------------------------------//
+
+// Dispatch all queued Steamworks callbacks.
+//
+// This is safe to call from multiple threads simultaneously,
+// but if you choose to do this, callback code could be executed on any thread.
+// One alternative is to call SteamAPI_RunCallbacks from the main thread only,
+// and call SteamAPI_ReleaseCurrentThreadMemory regularly on other threads.
