cudaError_t cudaEventSynchronize ( cudaEvent_t event )

Wait until the completion of all device work preceding the most recent call to cudaEventRecord() (in the appropriate compute streams, as specified by the arguments to cudaEventRecord()).

If cudaEventRecord() has not been called on event, cudaSuccess is returned immediately.

Waiting for an event that was created with the cudaEventBlockingSync flag will cause the calling CPU thread to block until the event has been completed by the device. If the cudaEventBlockingSync flag has not been set, then the CPU thread will busy-wait until the event has been completed by the device.

Parameters:

event

- Event to wait for

Returns:: cudaSuccess, cudaErrorInitializationError, cudaErrorInvalidValue, cudaErrorInvalidResourceHandle, cudaErrorLaunchFailure

Note:: Note that this function may also return error codes from previous, asynchronous launches.
