[Mesa3d-users] When to include <gl.h> and <glext.h>?

[vinit b. <ban...@gm...>]

Hi Brian,
I have one basic question.
I am using MESA 7.4 in my test application which uses openGL 1.1 as well as
2.0 program.

I am little confused about when to include <gl.h> and when <glext.h>

My understanding is:
for openGL 1.1/1.2/1.3  include<gl.h>

otherwise for higher version:
include <glext.h>

just like we have gl.h and gl2.h, same in MESA we have gl.h and glext.h?

correct me if i am wrong.

Thanks & Regards
Vinit
