D3DHAL_GLOBALDRIVERDATA structure (d3dhal.h)
The D3DHAL_GLOBALDRIVERDATA structure specifies the 3D capabilities of the driver and its device.
Syntax
typedef struct _D3DHAL_GLOBALDRIVERDATA {
DWORD dwSize;
D3DDEVICEDESC_V1 hwCaps;
DWORD dwNumVertices;
DWORD dwNumClipVertices;
DWORD dwNumTextureFormats;
LPDDSURFACEDESC lpTextureFormats;
} D3DHAL_GLOBALDRIVERDATA;
Members
dwSize
Specifies the size in bytes of this D3DHAL_GLOBALDRIVERDATA structure.
hwCaps
Specifies a D3DDEVICEDESC_V1 structure where the driver should return its hardware capabilities.
dwNumVertices
Reserved for system use and should be set to zero by the driver.
dwNumClipVertices
Reserved for system use and should be set to zero by the driver.
dwNumTextureFormats
Specifies the number of DDSURFACEDESC structures that lpTextureFormats points to.
lpTextureFormats
Points to an array of DDSURFACEDESC structures where the driver should return the texture formats supported by the device.
Remarks
The driver is responsible for allocating space for and setting all members of this structure. The driver returns a pointer to this structure in the lpD3DGlobalDriverData member of the DD_HALINFO structure, which is passed to the driver's DrvGetDirectDrawInfo function during driver initialization.
