//	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().
