OpenGL 2.0 API files

Hi all,
I need OpenGL 2.0 API files.

  1. Opengl 2.0 API files are free or license base?
    If it is free could you please share the like where OpenGL2.0 API files get.

Thanks in advance.

On Windows, header files are normally distributed with the compiler or IDE, or an add-on package from the same source as the compiler or IDE. There are some additional headers here, but they don’t include the main <GL/gl.h> header. On Linux, there will be a package for them, but the name varies wildly between distributions.
