> This does not work for me. I added it to the Init function of my render engine (as I know that at this time I have a valid OpenGL context) to no avail. My code keeps crashing at

glIsBufferARB function is loaded by Load_GL_ARB_vertex_buffer_object
call it on Render engine initialization.

i'm not sure, if you neet ARB function, since it's extension function,
rather than OpenGL version function.
Anyway, you might want to use glIsBuffer function, it's loaded by
calling Load_GL_version_1_5

hope it helps.
