D3DEnumTextureFormatsCallback

The D3DEnumTextureFormatsCallback function is an application-defined callback function for the IDirect3DDevice::EnumTextureFormats and IDirect3DDevice2::EnumTextureFormats methods.

HRESULT CALLBACK D3DEnumTextureFormatsCallback(
  LPDDSURFACEDESC lpDdsd,  
  LPVOID lpUserArg          
);
 

Parameters

lpDdsd

Address of a DDSURFACEDESC structure containing the texture information.

lpUserArg

Address of application-defined data passed to this callback function.

Return Values

Applications should return D3DENUMRET_OK to continue the enumeration, or D3DENUMRET_CANCEL to cancel it.

Remarks

When determining the order in which to call callback functions, the system searches the objects highest in the hierarchy first, and then calls their callback functions in the order in which they were created.

The LPD3DENUMTEXTUREFORMATSCALLBACK data type is defined as a pointer to this callback function:

typedef HRESULT (WINAPI* LPD3DENUMTEXTUREFORMATSCALLBACK)(LPDDSURFACEDESC lpDdsd, LPVOID lpContext);
