Function hipStreamWaitEvent 

pub unsafe extern "C" fn hipStreamWaitEvent(
    stream: hipStream_t,
    event: hipEvent_t,
    flags: c_uint,
) -> hipError_t

@brief Makes the specified compute stream wait for the specified event

@param[in] stream Stream to make wait @param[in] event Event to wait on @param[in] flags Parameters to control the operation

@returns #hipSuccess, #hipErrorInvalidHandle, #hipErrorInvalidValue, #hipErrorStreamCaptureIsolation

This function inserts a wait operation into the specified stream. All future work submitted to @p stream will wait until @p event reports completion before beginning execution.

Flags include: hipEventWaitDefault: Default event creation flag. hipEventWaitExternal: Wait is captured in the graph as an external event node when performing stream capture

This function only waits for commands in the current stream to complete. Notably, this function does not implicitly wait for commands in the default stream to complete, even if the specified stream is created with hipStreamNonBlocking = 0.
