# coroutines

[William Reed]

trying to understand what happens when a coroutine is launched in an IO dispatcher (to help in code review). my co-worker has code that launches in an IO dispatcher with code that has no suspend functions (mostly to conform to a previous interface, but lets hand wave that part). since there are no suspend functions, does calling this method always start a new thread?

i’m not familiar with the IO dispatcher internals and even though its well documented code there is a lot of it to look through

[William Reed]

does it ever start a new thread if these are the only kind of coroutines called?

to be more specific they launch multiple coroutines in this fashion so im trying to understand the threading implications

Look at the KDoc of <http://Dispatchers.IO|Dispatchers.IO>, it should answer your questions.

yes it switches the execution context to IO. It just never suspend
