Returns in *pWidth, *pHeight, and *pDepth the dimensions of the subresource of the mapped Direct3D resource pResource, which corresponds to Face and Level.
Because anti-aliased surfaces may have multiple samples per pixel, it is possible that the dimensions of a resource will be an integer factor larger than the dimensions reported by the Direct3D runtime.
The parameters pWidth, pHeight, and pDepth are optional. For 2D surfaces, the value returned in *pDepth will be 0.
If pResource is not of type IDirect3DBaseTexture9 or IDirect3DSurface9 or if pResource has not been registered for use with CUDA, then CUDA_ERROR_INVALID_HANDLE is returned.
For usage requirements of Face and Level parameters, see cuD3D9ResourceGetMappedPointer().
- Parameters:
-
| pWidth | - Returned width of surface |
| pHeight | - Returned height of surface |
| pDepth | - Returned depth of surface |
| pResource | - Registered resource to access |
| Face | - Face of resource to access |
| Level | - Level of resource to access |
- Returns:
- CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED, CUDA_ERROR_INVALID_CONTEXT, CUDA_ERROR_INVALID_VALUE, CUDA_ERROR_INVALID_HANDLE
- Note:
- Note that this function may also return error codes from previous, asynchronous launches.
