C - sleep() in threads gives problems

may help you . printf is line buffered, meaning it won't flush the buffer to screen until it reaches a newline "\n", or when the buffer is full. When you don't sleep, the buffer fills up quickly and prints to screen when it gets full, but when you do sleep it will take a long time for the buffer to fill, and so you never see anything on screen. Try changing that to printf("aaa\n");, or add an fflush(stdout); after the printf. See more information here: Why does printf not flush after the call unless a newline is in the format string?

it fixes the issue I wrote this function that handles the "rate limit error" of a Tweepy's cursor in order to keep downloading from Twitter APIs. , Try doing it like this instead:
code :
import threading
dummy_event = threading.Event()
dummy_event.wait(timeout=1)

Does Thread.sleep(milis) function make all Threads sleep?

I hope this helps . Thread.sleep() makes the current thread sleep. This is spelled out in the Javadoc:

seems to work fine Without the sleep statement the statement obj.exit(); will be very likely be executed before all of your threads reaching their wait status. ie. the notifyAll call will be over before at least one of your thread is in wait status. So at least one of your threads will be stuck in wait status waiting for some other thread to notify it and wake up. But that will never happen as obj.exit() is already finished.
With your sleep statement in place , all of your threads will get a chance to reach their wait status and your notifyAll call after the sleep will wake them all, The order of waking up will not be deterministic and will be handled by the thread scheduler.

Thread.sleep() in a AsyncTask sleep other background threads

seems to work fine Thread.sleep() will pause all other AsyncTasks running on the same default thread pool, not Threads.
In Android by default all AsyncTasks are executed on one default ThreadPool, which has 1 Thread. This way they are executed 1 by 1 in background.
code :
task.executeOnExecutor(AsyncTask.THREAD_POOL_EXECUTOR);
