SetWindowLongPtr

[elvman]

Today I browsed the Irrlicht source and found this function:

Code: Select all

irr::CIrrDeviceWin32* getDeviceFromHWnd(HWND hWnd)
{
	irr::core::list<SEnvMapper>::Iterator it = EnvMap.begin();
	for (; it!= EnvMap.end(); ++it)
		if ((*it).hWnd == hWnd)
			return (*it).irrDev;

	return 0;
}

Wouldn't it be faster to use this function: http://msdn.microsoft.com/en-us/library ... S.85).aspx with GWLP_USERDATA?

It _might_ be faster, but it would present problems if you want that GWLP_USERDATA value to be available for use by the application.
