GL fragment shaders 101

Question

I want to add a GLSL fragment shader to a program of mine, however I have been unable to find comprehensive documentation related to the C language (not C++ or C#). Anyone has examples or steps to get the ARB extension for shaders, or some sort of "hello world" template? I don't need help on the shaders themselves, just how to get them running into a C program, and more specifically on the commands required.

Answer 1

This is the tutorial I learned shaders from. If I recall, the tutorial is C friendly. It covers both ARB and OpenGL 2.0 function methods.
