Increments the usage count of the context and passes back a context handle in *pctx that must be passed to cuCtxDetach() when the application is done with the context. cuCtxAttach() fails if there is no context current to the thread.
Currently, the flags parameter must be 0.
- Parameters:
-
| pctx | - Returned context handle of the current context |
| flags | - Context attach flags (must be 0) |
- Returns:
- CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED, CUDA_ERROR_INVALID_CONTEXT, CUDA_ERROR_INVALID_VALUE
- Note:
- Note that this function may also return error codes from previous, asynchronous launches.
