event: *mut CUevent_st
) -> cudaError
Expand description
\brief Queries an event’s status
Queries the status of all work currently captured by \p event. See ::cudaEventRecord() for details on what is captured by an event.
Returns ::cudaSuccess if all captured work has been completed, or ::cudaErrorNotReady if any captured work is incomplete.
For the purposes of Unified Memory, a return value of ::cudaSuccess is equivalent to having called ::cudaEventSynchronize().
