Does HOpenGL 2.2.3.0 have a binding for glGetBufferParameteriv, or at least an interface that provides the same functionality, in particular querying the size of a vertex buffer object? I haven't been able to locate something suitable through the index, but may be missing a combination. [By way of explanation, I'm currently running into a segmentation fault with a program that attempts to use a "large" vertex buffer object, ~500MB. Its likely the bufferData request exceeds resources, but I'm trying to confirm this, and the usual method seems to be calling glGetBufferParameteriv with GL_BUFFER_SIZE as an arg. If there is another way of checking vertex buffer allocation, that would also be useful to know ...]. thanks, David -- Dr. David Duke E: djd@comp.leeds.ac.uk School of Computing W: www.comp.leeds.ac.uk/djd/ University of Leeds T: +44 113 3436800 Leeds, LS2 9JT, U.K.
