Returns in *pDevPtr the base pointer of the subresource of the mapped Direct3D resource pResource, which corresponds to Face and Level. The value set in pDevPtr may change every time that pResource is mapped.
If pResource is not registered, then CUDA_ERROR_INVALID_HANDLE is returned. If pResource was not registered with usage flags CU_D3D9_REGISTER_FLAGS_NONE, then CUDA_ERROR_INVALID_HANDLE is returned. If pResource is not mapped, then CUDA_ERROR_NOT_MAPPED is returned.
If pResource is of type IDirect3DCubeTexture9, then Face must one of the values enumerated by type D3DCUBEMAP_FACES. For all other types Face must be 0. If Face is invalid, then CUDA_ERROR_INVALID_VALUE is returned.
If pResource is of type IDirect3DBaseTexture9, then Level must correspond to a valid mipmap level. At present only mipmap level 0 is supported. For all other types Level must be 0. If Level is invalid, then CUDA_ERROR_INVALID_VALUE is returned.
- Parameters:
-
| pDevPtr | - Returned pointer corresponding to subresource |
| pResource | - Mapped 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, CUDA_ERROR_NOT_MAPPED
- Note:
- Note that this function may also return error codes from previous, asynchronous launches.
