I guess it would be possible to have non-critical variables defined in the driver backend, say. > Forgot to say, the offsets are obviously constant (until you dlclose the > library which declares them). > If they weren't, one couldn't keep pointers to __thread variables around > in IE/LE models. The variables could move in the dynamic case, hence the function call to get their address. We're trying to avoid that, obviously :-) -- Gareth Hughes ([EMAIL PROTECTED]) OpenGL Developer, NVIDIA Corporation
