118 Module Documentation3.23.2.4 CUresult cuEventQuery (CUevent hEvent)Returns CUDA_SUCCESS if the event has actually been recorded, or CUDA_ERROR_NOT_READY if not. IfcuEventRecord() has not been called on this event, the function returns CUDA_ERROR_INVALID_VALUE.Parameters:hEvent - Event to queryReturns:Note:CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED, CUDA_-ERROR_INVALID_CONTEXT, CUDA_ERROR_INVALID_HANDLE, CUDA_ERROR_INVALID_VALUE,CUDA_ERROR_NOT_READYSee also:Note that this function may also return error codes from previous, asynchronous launches.cuEventCreate, cuEventRecord, cuEventSynchronize, cuEventDestroy, cuEventElapsedTime3.23.2.5 CUresult cuEventRecord (CUevent hEvent, CUstream hStream)Records an event. If stream is non-zero, the event is recorded after all preceding operations in the stream have beencompleted; otherwise, it is recorded after all preceding operations in the CUDA context have been completed. Sinceoperation is asynchronous, cuEventQuery() and/or cuEventSynchronize() must be used to determine when the eventhas 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 recordhStream - Stream to record event forReturns:Note:CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED, CUDA_-ERROR_INVALID_CONTEXT, CUDA_ERROR_INVALID_HANDLE, CUDA_ERROR_INVALID_VALUESee also:Note that this function may also return error codes from previous, asynchronous launches.cuEventCreate, cuEventQuery, cuEventSynchronize, cuEventDestroy, cuEventElapsedTime3.23.2.6 CUresult cuEventSynchronize (CUevent hEvent)Waits until the event has actually been recorded. If cuEventRecord() has been called on this event, the function returnsCUDA_ERROR_INVALID_VALUE.If cuEventRecord() has previously been called and the event has not been recorded yet, this function returns CUDA_-ERROR_INVALID_VALUE.Generated on Wed Apr 1 16:11:42 2009 for NVIDIA CUDA Library by Doxygen
