Members

  • dwSize**
    Size of the structure. This parameter must be initialized before the structure is used.

  • dwFlags
    Indicates whether the DirectDraw functions are implemented.

    The following table shows the possible flags.

    Flag Description
    DDHAL_CB32_CANCREATESURFACE Indicates whether the CanCreateSurface callback function is implemented.
    DDHAL_CB32_CREATEPALETTE Indicates whether the CreatePalette callback function is implemented.
    DDHAL_CB32_CREATESURFACE Indicates whether the CreateSurface callback function is implemented.
    DDHAL_CB32_DESTROYDRIVER Indicates whether the DestroyDriver callback function is implemented.
    DDHAL_CB32_FLIPTOGDISURFACE Indicates whether the FlipToGDISurface callback function is implemented
    DDHAL_CB32_GETSCANLINE Indicates whether the GetScanLine callback function is implemented.
    DDHAL_CB32_SETEXCLUSIVEMODE Indicates whether the SetExclusiveMode callback function is implemented.
    DDHAL_CB32_SETMODE Indicates whether the SetMode callback function is implemented.
    DDHAL_CB32_WAITFORVERTICALBLANK Indicates whether the WaitForVerticalBlank callback function is implemented.

  • DestroyDriver
    Pointer to the driver's implementation of the DestroyDriver callback function.

  • CreateSurface**
    Pointer to the driver's implementation of the CreateSurface callback function.

  • SetColorKey**
    This member is obsolete and should not be used.

  • SetMode**
    Pointer to the driver's implementation of the SetMode callback function.

  • WaitForVerticalBlank**
    Pointer to the driver's implementation of the WaitForVerticalBlank callback function.

  • CanCreateSurface**
    Pointer to the driver's implementation of the CanCreateSurface callback function.

  • CreatePalette**
    Pointer to the driver's implementation of the CreatePalette callback function.

  • GetScanLine**
    Pointer to the driver's implementation of the GetScanLine callback function.

  • SetExclusiveMode**
