glBufferData fails silently with overly large sizes

Question

hi everybody,

i just noticed, that glBufferData fails silently when i try to call it with size: 1085859108 and data: NULL.

Following calls to glBufferSubData fail with a OUT_OF_MEMORY 'Exception'. This is on Windows XP 32bit, NVIDIA Gforce 9500 GT (1024MB) and 195.62 Drivers.

Is there any way to determinate if a buffer was created sucessfully? (Something like a proxy texture for example?)

kind regards, Florian

Answer 1

I doubt that it's really silent. I'd guess that glGetError would return GL_OUT_OF_MEMORY after that attempt.
