CUptiResult cuptiActivityGetNumDroppedRecords (CUcontextcontext, uint32_t streamId, size_t ∗ dropped)Get the number of records that were dropped from a queue because all the buffers in thequeue are full. See cuptiActivityEnqueueBuffer() for description of queues. Calling thisfunction does not transfer ownership of the buffer. The dropped count maintained for thequeue is reset to zero when this function is called.Parameters:context The context, or NULL to get dropped count from global queuestreamId The stream IDdropped The number of records that were dropped since the last call to this function.Return values:CUPTI_SUCCESSCUPTI_ERROR_NOT_INITIALIZEDCUPTI_ERROR_INVALID_PARAMETER if dropped is NULLCUptiResult cuptiActivityQueryBuffer (CUcontext context, uint32_tstreamId, size_t ∗ validBufferSizeBytes)Query the status of buffer at the head in the queue. See cuptiActivityEnqueueBuffer() fordescription of queues. Calling this function does not transfer ownership of the buffer.Parameters:context The context, or NULL to query the global queuestreamId The stream IDvalidBufferSizeBytes Returns the number of bytes in the buffer that contain activityrecordsReturn values:CUPTI_SUCCESSCUPTI_ERROR_NOT_INITIALIZEDCUPTI_ERROR_INVALID_PARAMETER if buffer or validBufferSizeBytesare NULLCUPTI_ERROR_MAX_LIMIT_REACHED if buffer is fullCUPTI_ERROR_QUEUE_EMPTY the queue is empty, validBufferSizeBytesreturns 0CUDA Tools SDK CUPTI User’s Guide DA-05679-001_v01 | 40
CUptiResult cuptiGetStreamId (CUcontext context, CUstreamstream, uint32_t ∗ streamId)Get the ID of a stream. The stream ID is needed to enqueue and dequeue activity recordbuffers on a stream queue.Parameters:context The context containing the streamstream The streamstreamId Returns the ID for the streamReturn values:CUPTI_SUCCESSCUPTI_ERROR_NOT_INITIALIZEDCUPTI_ERROR_INVALID_PARAMETER if streamId is NULLSee also:cuptiActivityEnqueueBuffercuptiActivityDequeueBufferCUDA Tools SDK CUPTI User’s Guide DA-05679-001_v01 | 41
