| /* |
| * This file manages the OpenGL API dispatch layer. |
| * The dispatch table (struct _glapi_table) is basically just a list |
| * of function pointers. |
| * There are functions to set/get the current dispatch table for the |
| * current thread and to manage registration/dispatch of dynamically |
| * added extension functions. |
| * |
| * It's intended that this file and the other glapi*.[ch] files are |
| * flexible enough to be reused in several places: XFree86, DRI- |
| * based libGL.so, and perhaps the SGI SI. |
| * |
| * NOTE: There are no dependencies on Mesa in this code. |
| * |
| * Versions (API changes): |
| * 2000/02/23 - original version for Mesa 3.3 and XFree86 4.0 |
| * 2001/01/16 - added dispatch override feature for Mesa 3.5 |
| * 2002/06/28 - added _glapi_set_warning_func(), Mesa 4.1. |
| * 2002/10/01 - _glapi_get_proc_address() will now generate new entrypoints |
| * itself (using offset ~0). _glapi_add_entrypoint() can be |
| * called afterward and it'll fill in the correct dispatch |
| * offset. This allows DRI libGL to avoid probing for DRI |
| * drivers! No changes to the public glapi interface. |

| * \name Current dispatch and current context control variables |
| * |
| * Depending on whether or not multithreading is support, and the type of |
| * support available, several variables are used to store the current context |
| * pointer and the current dispatch table pointer. In the non-threaded case, |
| * the variables \c _glapi_Dispatch and \c _glapi_Context are used for this |
| * purpose. |
| * |
| * In the "normal" threaded case, the variables \c _glapi_Dispatch and |
| * \c _glapi_Context will be \c NULL if an application is detected as being |
| * multithreaded. Single-threaded applications will use \c _glapi_Dispatch |
| * and \c _glapi_Context just like the case without any threading support. |
| * When \c _glapi_Dispatch and \c _glapi_Context are \c NULL, the thread state |
| * data \c _gl_DispatchTSD and \c ContextTSD are used. Drivers and the |
| * static dispatch functions access these variables via \c _glapi_get_dispatch |
| * and \c _glapi_get_context. |
| * |
| * There is a race condition in setting \c _glapi_Dispatch to \c NULL. It is |
| * possible for the original thread to be setting it at the same instant a new |
| * thread, perhaps running on a different processor, is clearing it. Because |
| * of that, \c ThreadSafe, which can only ever be changed to \c GL_TRUE, is |
| * used to determine whether or not the application is multithreaded. |
| * |
| * In the TLS case, the variables \c _glapi_Dispatch and \c _glapi_Context are |
| * hardcoded to \c NULL. Instead the TLS variables \c _glapi_tls_Dispatch and |
| * \c _glapi_tls_Context are used. Having \c _glapi_Dispatch and |
| * \c _glapi_Context be hardcoded to \c NULL maintains binary compatability |
| * between TLS enabled loaders and non-TLS DRI drivers. |
