hipError_t hipEventRecord ( hipEvent_t  event,
hipStream_t  stream 
)
friend

Record an event in the specified stream.

Parameters
[in]eventevent to record.
[in]streamstream in which to record event.
Returns
#hipSuccess, #hipErrorInvalidValue, #hipErrorInitializationError, #hipErrorInvalidResourceHandle, #hipErrorLaunchFailure

hipEventQuery() or hipEventSynchronize() must be used to determine when the event transitions from "recording" (after hipEventRecord() is called) to "recorded" (when timestamps are set, if requested).

Events which are recorded in a non-NULL stream will transition to from recording to "recorded" state when they reach the head of the specified stream, after all previous commands in that stream have completed executing.

If hipEventRecord() has been previously called on this event, then this call will overwrite any existing state in event.

If this function is called on a an event that is currently being recorded, results are undefined

  • either outstanding recording may save state into the event, and the order is not guaranteed.
