Query the status of all device work preceding the most recent call to cuEventRecord() (in the appropriate compute streams, as specified by the arguments to cuEventRecord()).
If this work has successfully been completed by the device, or if cuEventRecord() has not been called on hEvent, then CUDA_SUCCESS is returned. If this work has not yet been completed by the device then CUDA_ERROR_NOT_READY is returned.
- Parameters:
-
- Returns:
- CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED, CUDA_ERROR_INVALID_HANDLE, CUDA_ERROR_INVALID_VALUE, CUDA_ERROR_NOT_READY
- Note:
- Note that this function may also return error codes from previous, asynchronous launches.
