Please don’t re-post.

Check the documentation for your development environment on what specific error codes mean, as there is nothing OpenGL specific in your question.

Just to give you a random sample of how this works in another languages (Visual C++):

cd “\Program Files\Microsoft Visual Studio\VC98\Include\GL”
grep 501 GL.h
#define GL_INVALID_VALUE 0x0501
