Since both front and back buffers will * return the same structure, you need to be able to distinguish * somewhere what kind of buffer (front/back) was being asked for, so * that ddx can render to the right place. That's the problem that the * following code solves. Note: we couldn't embed this in the LookupID* * functions because the VALIDATE_DRAWABLE_AND_GC macro often circumvents * those functions by checking a one-element cache. That's why we're * mucking with VALIDATE_DRAWABLE_AND_GC. * * If you put -DNEED_DBE_BUF_BITS into PervasiveDBEDefines, the window * structure will have two additional bits defined, srcBuffer and * dstBuffer, and their values will be maintained via the macros * SET_DBE_DSTBUF and SET_DBE_SRCBUF (below). If you also * put -DNEED_DBE_BUF_VALIDATE into PervasiveDBEDefines, the function * DbeValidateBuffer will be called any time the bits change to give you * a chance to do some setup. See the DBE code for more details on this * function. We put in these levels of conditionality so that you can do * just what you need to do, and no more. If neither of these defines * are used, the bits won't be there, and VALIDATE_DRAWABLE_AND_GC will * be unchanged. dpw */ #if defined(NEED_DBE_BUF_BITS) #define SET_DBE_DSTBUF(_pDraw, _drawID) \ SET_DBE_BUF(_pDraw, _drawID, dstBuffer, TRUE) #define SET_DBE_SRCBUF(_pDraw, _drawID) \ SET_DBE_BUF(_pDraw, _drawID, srcBuffer, FALSE) #if defined (NEED_DBE_BUF_VALIDATE) #define SET_DBE_BUF(_pDraw, _drawID, _whichBuffer, _dstbuf) \ if (_pDraw->type == DRAWABLE_WINDOW)\ {\ int thisbuf = (_pDraw->id == _drawID);\ if (thisbuf != ((WindowPtr)_pDraw)->_whichBuffer)\ {\ ((WindowPtr)_pDraw)->_whichBuffer = thisbuf;\ DbeValidateBuffer((WindowPtr)_pDraw, _drawID, _dstbuf);\ }\ } #else /* want buffer bits, but don't need to call DbeValidateBuffer */ #define SET_DBE_BUF(_pDraw, _drawID, _whichBuffer, _dstbuf) \ if (_pDraw->type == DRAWABLE_WINDOW)\ {\ ((WindowPtr)_pDraw)->_whichBuffer = (_pDraw->id == _drawID);\ } #endif /* NEED_DBE_BUF_VALIDATE */ #else /* don't want buffer bits in window */ #define SET_DBE_DSTBUF(_pDraw, _drawID) /**/ #define SET_DBE_SRCBUF(_pDraw, _drawID) /**/ #endif /* NEED_DBE_BUF_BITS */ #define VALIDATE_DRAWABLE_AND_GC(drawID, pDraw, pGC, client)\ if ((stuff->gc == INVALID) || (client->lastGCID != stuff->gc) ||\ (client->lastDrawableID != drawID))\ {\ SECURITY_VERIFY_GEOMETRABLE(pDraw, drawID, client, SecurityWriteAccess);\ SECURITY_VERIFY_GC(pGC, stuff->gc, client, SecurityReadAccess);\ if ((pGC->depth != pDraw->depth) ||\ (pGC->pScreen != pDraw->pScreen))\ return (BadMatch);\ client->lastDrawable = pDraw;\ client->lastDrawableID = drawID;\ client->lastGC = pGC;\ client->lastGCID = stuff->gc;\ }\ else\ {\ pGC = client->lastGC;\ pDraw = client->lastDrawable;\ }\ SET_DBE_DSTBUF(pDraw, drawID);\ if (pGC->serialNumber != pDraw->serialNumber)\ ValidateGC(pDraw, pGC);
