Reference pages for DirectDraw driver functions, callbacks, and structures can be found in DirectDraw Driver Functions and DirectDraw Driver Structures.įor more information about DirectDraw, see the Windows SDK. The Windows Driver Development Kit (DDK) also contains sample code for a DirectDraw driver in the p3samp video display directory. The interfaces are generalized so the program can change which interface it uses at startup and still render properely.
To see whether applicable driver updates are available, visit the. This is a Multithreaded graphic engine capable of Direct3D, DirectDraw or GDI graphics with Hardware and software implementations. The ddraw.h header file is shipped with the Windows SDK all other header files are included with the Windows Driver Kit (WDK). If the issue continues to occur, go to the next method. This header file maps names that are different on the two platforms.
DirectDraw, in turn, calls upon the DxApi interface.ĭmemmgr.h is used when the driver wants to perform its own memory management instead of relying on the DirectDraw runtime.ĭdkernel.h is used when the driver includes kernel-mode support.ĭx95type.h allows driver writers to easily port existing Windows 98/Me drivers to Windows 2000 and later. The issue is a graphics card problem where your card is too powerful for the game. The reader should be familiar with the DirectDraw APIs, and have a firm grasp of the Windows 2000 display driver model.ĭriver writers who are creating Microsoft DirectDraw drivers for Microsoft Windows 2000 and later should use the following header files:ĭdrawint.h contains the basic types, constants, and structures for DirectDraw drivers.ĭdraw.h contains the basic types, constants, and structures used by both applications and drivers.ĭvp.h is used when the driver supports the DirectDraw video port extensions (VPE).ĭxmini.h is used when the video miniport driver includes support for kernel-mode video transport, the DxApi interface (functions specified by the DXAPI_INTERFACE structure).ĭdkmapi.h is used by video capture drivers to access the DxApi function.
The guidelines are written for Microsoft Windows 2000 and later. This is not in any way a complete implementation of the DirectDraw library. Many unused functions are partially implemented and commented for future development, some are left as unimplemented. Note that this package does not modify the DirectX Runtime installed on your Windows OS in any way. DirectDraw functions actually used by the game are implemented in a minimalist way. This section describes the Microsoft DirectDraw interface and architecture, and provides implementation guidelines for DirectDraw driver writers. The Microsoft DirectX End-User Runtime installs a number of runtime libraries from the legacy DirectX SDK for some games that use D3DX9, D3DX10, D3DX11, XAudio 2.7, XInput 1.3, XACT, and/or Managed DirectX 1.1.
