Hello how could I make a function repeatable after a period of time using coroutines?

Do you want the function to repeat itself on a timer, or to filter calls faster than a certain period?

[otakusenpai]

on a timer

Something like this would be useful: https://github.com/Kotlin/kotlinx.coroutines/blob/master/docs/channels.md#building-channel-producers

how could i set the time period to execute after?
Suppose i hav a function foo() and want to excute foo() after 40s and this call does some kind of i/o

[enleur]

create a ticker channel that will emit message after 40s and then close the channel

[otakusenpai]

suspend fun CoroutineScope.updateChannelList()  { 
        
}

This is the function signature that I have as of now. But the signature expected by withTimeoutOrNull is different.
Can you give a sample ?

Is sending to a ticker channel only one time procedure or should it be done multiple times?
