I am a bit confused as to how some people refer getting pointers to core functions of OpenGL 3.0 and above as "loading OpenGL extensions"...
When I get output of glGetString(GL_EXTENSIONS) it returns me functions which are indeed extensions...
Is there a way to get similar information about core functions? Or should I either trust that they are there if I successfully create a suitable context or check them individually.
Have I understood it right that the extensions actually are some "special" functions and features that a graphics card may support and that feature might or might not someday be approved by ARB?
