At some point in time startRetrieveCall will change the value of isAttempting. How can I wait for the condition to be fulfilled without having to make a recursive call?

tailrec suspend fun call() : SomeObject =
        if (!isAttempting)
            startRetrievingCall()
        else
            call()

Mutex

maybe? lock the mutex before

startRetrievingCall

, then lock it again after the call. This will suspend. In

startRetrievingCall

, at some point unlock the mutex, which will resume the original

call

point. Though to be honest, this looks like an XY situation, and you might be better served by

async

+

Deferred

, or a

Channel

After investigating all the options I think Mutex is the solution
