## Chapter 4. Defined Constants and Associated Commands

This chapter lists all the defined constants in OpenGL and their corresponding commands; these constants might indicate a parameter name, a value for a parameter, a mode, a query target, or a return value. The list is intended to be used as another index into the reference pages: if you remember the name of a constant, you can use this table to find out which functions use it, and then you can refer to the reference pages for those functions for more information. Note that all the constants listed can be used directly by the corresponding commands; the reference pages list additional, related commands that might be of interest.
