Creates a new CUDA context, initializes VDPAU interoperability, and associates the CUDA context with the calling thread. It must be called before performing any other VDPAU interoperability operations. It may fail if the needed VDPAU driver facilities are not available. For usage of the flags parameter, see cuCtxCreate().
- Parameters:
-
| pCtx | - Returned CUDA context |
| flags | - Options for CUDA context creation |
| device | - Device on which to create the context |
| vdpDevice | - The VdpDevice to interop with |
| vdpGetProcAddress | - VDPAU's VdpGetProcAddress function pointer |
- Returns:
- CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED, CUDA_ERROR_INVALID_CONTEXT, CUDA_ERROR_INVALID_VALUE, CUDA_ERROR_OUT_OF_MEMORY
- Note:
- Note that this function may also return error codes from previous, asynchronous launches.
