Pixel placement and Bitmap placement with OpenGL

I am writing in Borland c++ 5 and I just got hold of some code to initilize opengl in a window. I have no idea what any of the functions do. Could anyone email or post a basic list of functions like pixel placement, bitmap placement, clearing the buffer, double buffer techniches, ect? Thanks! Email it to dplock@pacbell.net.

Basically I am just looking for a SIMPLE yet fast way to put down pixels and bitmaps on a 2D fullscreen mode. I have never done opengl before so if you could explain everything thats being passed into the functions that would be great. I need:
Double Buffer
Pixel Placemnt
Algorithum or Functions for Bitmap placement
Clearing the screen


Sorry, i forgot one more thing. How about bitmap rotation and scaling. Thanks again.
