    Extension Refernce Functions

    Hi... I'm totally new to opengl extensions and I am having a hard time finding a reference for the syntax. I know how to declare them and call them once i have them. I am also aware of how to check if they are supported.

    But for example... the function below seems strait forward to me at first.

    I want to be able to get the pointer to my buffer so I can use an offset one vertex data is loaded to the card...

    I would have though it needed 2 parameters but it takes three. And I'm uncertain on where to find the reference. Does one exist?

    The extension specifications are listed at

    Most of them also contain sample code.

    #define BUFFER_OFFSET(i) ((char *)NULL + (i))
