# coroutines

I want to launch 64 coroutines which will all be listening to a fan-out channel, I want the whole thing to suspend untill all 64 coroutines have been launched and are all listening to the channel, then I would return

You can use launch(start = CoroutineStart.UNDISPATCHED) and it will not return until the code in the coroutine suspends at the first suspension point.

But why would you need it?

[coder82]

the channel is rendevouz, and I start offering to it rather quickly, and the coroutines listening to such channel are still launching...

[coder82]

so i wanted to create a method which makes sure all are listening to channel before i procced so that i don't lose the initial offers to such channel

[coder82]

and i don't want to buffer the channel

[coder82]

i hope i makes sense 😄

[coder82]

thanks worked perfectly

If you’re using offer with a rendezvous channel, you still have a race condition and could lose items even if all coroutines are started.
