The code in dri_util.c - * gets compiled into each of the DRI 3D drivers. A typical DRI driver, - * is loaded dynamically by libGL, so libGL knows nothing about the - * internal functions here. On Mac OS X the AppleDRI driver code is - * statically linked into libGL, but otherwise it tries to behave like - * a standard DRI driver. - * - * The functions defined here are called from the GL library via function - * pointers in the __DRIdisplayRec, __DRIscreenRec, __DRIcontextRec, - * __DRIdrawableRec structures defined in glxclient.h. Those function - * pointers are initialized by code in this file. The process starts when - * libGL calls the __driCreateScreen() function at the end of this file. - * - * The above-mentioned DRI structures have no dependencies on Mesa. - * Each structure instead has a generic (void *) private pointer that - * points to a private structure. For Mesa drivers, these private - * structures are the __DRIdrawablePrivateRec, __DRIcontextPrivateRec, - * __DRIscreenPrivateRec, and __DRIvisualPrivateRec structures defined - * in dri_mesaint.h. We allocate and attach those structs here in - * this file. - */ - - -#ifdef GLX_DIRECT_RENDERING - -/* These are first to ensure that Apple's GL headers are used. */ -#include <OpenGL/OpenGL.h> -#include <OpenGL/CGLContext.h> - -#include <unistd.h> -#include <X11/Xlibint.h> -#include <X11/extensions/Xext.h> - -#define GLAPIENTRYP * -#include "extutil.h" -#include "glxclient.h" -#include "appledri.h" -#include "dri_driver.h" -#include "x-list.h" -#include "x-hash.h" - -/** - * This is used in a couple of places that call \c driMesaCreateNewDrawable. - */ -static const int empty_attribute_list[1] = { None };
