This section describes deprecated Direct3D 11 interoperability functionality.
Function Documentation
CUresult cuD3D11CtxCreate (CUcontext * pCtx, CUdevice * pCudaDevice, unsigned int Flags, ID3D11Device * pD3DDevice)
Deprecated
- This function is deprecated as of CUDA 5.0.
This function is deprecated and should no longer be used. It is no longer necessary to associate a CUDA context with a D3D11 device in order to achieve maximum interoperability performance.
Parameters:
-
pCtx - Returned newly created CUDA context
pCudaDevice - Returned pointer to the device on which the context was created
Flags - Context creation flags (see cuCtxCreate() for details)
pD3DDevice - Direct3D device to create interoperability context with
Returns:
- CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED, CUDA_ERROR_INVALID_VALUE, CUDA_ERROR_OUT_OF_MEMORY, CUDA_ERROR_UNKNOWN
Note:
- Note that this function may also return error codes from previous, asynchronous launches.

CUresult cuD3D11CtxCreateOnDevice (CUcontext * pCtx, unsigned int flags, ID3D11Device * pD3DDevice, CUdevice cudaDevice)
Deprecated
- This function is deprecated as of CUDA 5.0.
This function is deprecated and should no longer be used. It is no longer necessary to associate a CUDA context with a D3D11 device in order to achieve maximum interoperability performance.
Parameters:
-
pCtx - Returned newly created CUDA context
flags - Context creation flags (see cuCtxCreate() for details)
pD3DDevice - Direct3D device to create interoperability context with
cudaDevice - The CUDA device on which to create the context. This device must be among the devices returned when querying CU_D3D11_DEVICES_ALL from cuD3D11GetDevices.
Returns:
- CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED, CUDA_ERROR_INVALID_VALUE, CUDA_ERROR_OUT_OF_MEMORY, CUDA_ERROR_UNKNOWN
Note:
- Note that this function may also return error codes from previous, asynchronous launches.

CUresult cuD3D11GetDirect3DDevice (ID3D11Device ** ppD3DDevice)
Deprecated
- This function is deprecated as of CUDA 5.0.
This function is deprecated and should no longer be used. It is no longer necessary to associate a CUDA context with a D3D11 device in order to achieve maximum interoperability performance.
Parameters:
- ppD3DDevice - Returned Direct3D device corresponding to CUDA context
Returns:
- CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED, CUDA_ERROR_INVALID_CONTEXT
Note:
- Note that this function may also return error codes from previous, asynchronous launches.
