29 * This file manages the OpenGL API dispatch layer.
30 * The dispatch table (struct _glapi_table) is basically just a list
31 * of function pointers.
32 * There are functions to set/get the current dispatch table for the
33 * current thread and to manage registration/dispatch of dynamically
34 * added extension functions.
35 *
36 * It's intended that this file and the other glapi*.[ch] files are
37 * flexible enough to be reused in several places: XFree86, DRI-
38 * based libGL.so, and perhaps the SGI SI.
39 *
40 * There are no dependencies on Mesa in this code.
