//    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().
//----------------------------------------------------------------------------------------------------------------------------------------------------------//

// SteamAPI_RunCallbacks 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.
