Hi @ all;

my question for this time is, what is exactly the difference (expect from the parameter) between the ussage of “glGetString()” and this “wglGetExtensionStringARB()”-Extension, while querying the available extensions my graphic-card ?

I’m not sure, when to use which function; by the way: querying all available extensions on my graphic-card works fine if i use only “glGetString” !?
So i’m very interested in getting more information about these two functionalities.

bye

glGetString returns (among other things) the GL extensions supported.
wglGetExtensionStringARB returns the WGL extensions, eg WGL_ARB_pixel_format
