I'm trying to do an example with Buffer objects which were intdocued in 1.5, meaning I have to access them with extensions. I am using the glew library and it says I have support for opengl 20. Whenever I try to call glGenBuffers() it just doesn't work. After I call glIsBuffer() on the GLuint I passed to glGenBuffers() it doesn't come out at all. Do I have to do something else with the extension to get it to work? I tried to check to see if it was supported but can't seem to find it in the mass of enumerated variables for the extensions.
