It will crash in the AddRef code. Better to try to do something like that :
if (found == NULL) { TRACE("Did not find any valid surface\n"); *ppSurface = NULL; return DD_OK; }
Thanks, I will try it. But with the test disabled, I get no crash in AddRef (??). See the following resuslts : trace:ddraw:Main_DirectDrawSurface_GetAttachedSurface (0x402a9418)->Looking for caps: 4,0,1,1 output: 0x741ed0 Caps are : DDSCAPS_BACKBUFFER trace:ddraw:Main_DirectDrawSurface_GetAttachedSurface Surface: (0x402a9b38) caps: 1000601c,0,0,0 Surface caps are : DDSCAPS_BACKBUFFER DDSCAPS_COMPLEX DDSCAPS_FLIP DDSCAPS_3DDEVICE DDSCAPS_VIDEOMEMORY DDSCAPS_LOCALVIDMEM trace:ddraw:Main_DirectDrawSurface_GetAttachedSurface Returning surface 0x402a9b38 with description : - DDSD_CAPS : DDSCAPS_BACKBUFFER DDSCAPS_COMPLEX DDSCAPS_FLIP DDSCAPS_3DDEVICE DDSCAPS_VIDEOMEMORY DDSCAPS_LOCALVIDMEM - DDSD_HEIGHT : 480 - DDSD_WIDTH : 640 - DDSD_PITCH : 1280 - DDSD_LPSURFACE : 0x424b0000 - DDSD_PIXELFORMAT : ( DDPF_RGB , RGB bits: 16, R f800 G 07e0 B 001f) trace:ddraw:Main_DirectDrawSurface_AddRef (0x402a9b38)->(): increasing from 1 trace:ddraw:Main_DirectDrawSurface_AddAttachedSurface (0x402a9b38)->(0x402a90e8) trace:ddraw:Main_DirectDrawSurface_AddRef (0x402a90e8)->(): increasing from 1 The only err: that I get inddraw trace are unhandled dwRenderStateType.
Argh, cant do it for now.
To be 100 %, the best would be for one to do a test in real Windows and check what happens when asking for a non-existant attached surface and check what happens (ie DD_OK with ppSurface being NULL or DDERR_NOTFOUND).
The reason I write is that : in fact, I disabled the failing test
and
the game (Re-Volt Demo) begins to start.
Well, as said before, try to see if this call SHOULD fail or if it's a bug that we do not find this attached surface.
Even better would be to disassemble the code handling the return of this function to see what kind of stuff the game expects.
