| /** \file piglit-dispatch.h |
| * |
| * Dispatch mechanism providing Piglit with access to: |
| * |
| * - Enum values defined by OpenGL, GLES, and extensions. The enums |
| * are declared as simple #defines. |
| * |
| * - Functions defined by OpenGL, GLES, and extensions. Each function |
| * is represented by a function pointer, which initially points to a |
| * stub function. When the stub function is called, it looks up the |
| * appropriate function in the GL or GLES implementation, and |
| * updates the function pointer to point to it. Then it defers to |
| * that function. |
| * |
| * The dispatch mechanism understands function aliases. So, for |
| * example, since glMapBuffer and glMapBufferARB are synonymous, you |
| * may safely call either function. The dispatch mechanism will |
| * transparently map to whichever function the implementation |
| * supports. |
| * |
| * You may also translate a function name to a function pointer at run |
| * time by calling piglit_dispatch_resolve_function(). |
| * |
| * The dispatch mechanism must be initialized before its first use. |
| * The initialization function, piglit_dispatch_init(), allows the |
| * caller to specify which API is in use, how to look up function |
| * pointers, what to do in the event of an error, and what to do if an |
| * unsupported function is requested. |
