I've sent this bug report a little too quickly.
After sending it, I realized there might still be the option that I did not
use it correctly.
So after reading the documentation again, I finally understood these
functions should get a position list, which are obtained using
`event-start/event-end`.

So please close this bug.
Thanks you!
