- * This file is a template which generates the OpenGL API entry point
- * functions. It should be included by a .c file which first defines
- * the following macros:
- * KEYWORD1 - usually nothing, but might be __declspec(dllexport) on Win32
- * KEYWORD2 - usually nothing, but might be __stdcall on Win32
- * NAME(n) - builds the final function name (usually add "gl" prefix)
- * DISPATCH(func, args, msg) - code to do dispatch of named function.
- * msg is a printf-style debug message.
- * RETURN_DISPATCH(func, args, msg) - code to do dispatch with a return value
- *
- * Here is an example which generates the usual OpenGL functions:
- * #define KEYWORD1
- * #define KEYWORD2
- * #define NAME(func) gl##func
- * #define DISPATCH(func, args, msg) \\
- * struct _glapi_table *dispatch = CurrentDispatch; \\
- * (*dispatch->func) args
- * #define RETURN DISPATCH(func, args, msg) \\
- * struct _glapi_table *dispatch = CurrentDispatch; \\
- * return (*dispatch->func) args
