NAME
Direct3D 11 Interoperability [DEPRECATED] -Functions
cudaError_t cudaD3D11GetDirect3DDevice (ID3D11Device **ppD3D11Device)
Gets the Direct3D device against which the current CUDA context was created.
cudaError_t cudaD3D11SetDirect3DDevice (ID3D11Device *pD3D11Device, int device=-1)
Sets the Direct3D 11 device to use for interoperability with a CUDA device.
Detailed Description
This section describes deprecated Direct3D 11 interoperability functions.
Function Documentation
cudaError_t cudaD3D11GetDirect3DDevice (ID3D11Device ** ppD3D11Device)
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 device with a D3D11 device in order to achieve maximum interoperability performance.
Parameters:
- ppD3D11Device - Returns the Direct3D device for this thread
Returns:
- cudaSuccess, cudaErrorUnknown
Note:
- Note that this function may also return error codes from previous, asynchronous launches.

cudaError_t cudaD3D11SetDirect3DDevice (ID3D11Device * pD3D11Device, int device = -1)
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 device with a D3D11 device in order to achieve maximum interoperability performance.
Parameters:
-
pD3D11Device - Direct3D device to use for interoperability
device - The CUDA device to use. This device must be among the devices returned when querying cudaD3D11DeviceListAll from cudaD3D11GetDevices, may be set to -1 to automatically select an appropriate CUDA device.
Returns:
- cudaSuccess, cudaErrorInitializationError, cudaErrorInvalidValue, cudaErrorSetOnActiveProcess
Note:
- Note that this function may also return error codes from previous, asynchronous launches.
