hi.
I understand cyg_thread_delay make current thread sleep.
then who are going to wake the sleeped thread?
and after waken, the thread goes to READY mode or RUN mode ?
thanks in advance.
Tony.

I think the code for this is in the clock DSR

First the DSR wake up the thread so it's set to READY.
It maybe set to RUN whenever it is rescheduled, which may happened at
the end of the clock ISR, if the scheduler is not locked, and the thread
has an higher priority than any other READY thread.
