DDHAL Callbacks and Capabilities (Windows CE 5.0)
DirectDraw hardware abstraction layer (DDHAL) includes various callbacks and caps structures. Create each of these structures in a global variable and set them up when they are declared so DDGPE can access them at any time. Then, use these global variables when populating the DDHALINFO structure in your buildDDHALInfo implementation.
For more information on these structures, see DDHAL Callback Structures.
The following table shows the DDHAL callback structures and their corresponding sample variable names.
| Type | Sample variable name |
|---|---|
| DDHAL_DDCALLBACKS | cbDDCallbacks |
| DDHAL_DDPALETTECALLBACKS | cbDDPaletteCallbacks |
| DDHAL_DDSURFACECALLBACKS | cbDDSurfaceCallbacks |
| DDHAL_DDCOLORCONTROLCALLBACKS | ColorControlCallbacks |
| DDHAL_DDMISCELLANEOUSCALLBACKS | MiscellaneousCallbacks |
| DDHAL_DDMISCELLANEOUS2CALLBACKS | Miscellaneous2Callbacks |
| DDHAL_DDVIDEOPORTCALLBACKS | VideoPortCallbacks |
| DDMORECAPS | MoreCaps |
