Records an event. If stream is non-zero, the event is recorded after all preceding operations in the stream have been completed; otherwise, it is recorded after all preceding operations in the CUDA context have been completed. Since operation is asynchronous, cuEventQuery() and/or cuEventSynchronize() must be used to determine when the event has actually been recorded.
If cuEventRecord() has previously been called and the event has not been recorded yet, this function returns CUDA_ERROR_INVALID_VALUE.
- Parameters:
-
| hEvent | - Event to record |
| hStream | - Stream to record event for |
- Returns:
- CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED, CUDA_ERROR_INVALID_CONTEXT, CUDA_ERROR_INVALID_HANDLE, CUDA_ERROR_INVALID_VALUE
- Note:
- Note that this function may also return error codes from previous, asynchronous launches.

- cuEventCreate, cuEventQuery, cuEventSynchronize, cuEventDestroy, cuEventElapsedTime
