Both gl.spec and glext.h list three versions of this method: glProgramParameteri, glProgramParameteriARB and glProgramParameteriEXT. However, my driver (Nvidia) only exposes the last two. The first one is missing.
This issue can be reproduced on two different video cards (Quadro FX 570 and Quadro NVS 135M), using driver 195.62 on Windows 7 (both 32- and 64-bit). The driver claims 3.2 support, so I would expect the core version to be available.
Is this expected or are we dealing with a driver bug? Can anyone with an AMD video card say if this function is exposed there?
