[Jonathan]

Hmm... yes like from any other function...

fun foo() {
  launch { doSomethingUsefull() }
}

[Jonathan]

This doesn't wait for the doSomethingUsefull to complete and don't care if it does'nt work

[dai]

Thanks for the reply, yeah i need to do it with in the suspend

[dai]

thats my problem

[Jonathan]

suspend fun foo() {
  launch { doSomethingUsefull() }
}

[Jonathan]

why is it a problem ?

[dai]

Yeah I don’t think what I need is possible with some coroutines without it being a bit of a hack

[dai]

so going to rework things a bit

[dai]

thanks for the reply

Could you give a code example?

[bdawg.io]

The block passed to launch is a suspending function. The Job that is returned does not block the rest of your procedures until you invoke suspend fun join() on the job. Maybe I’m misunderstanding your example?

suspend fun foo() {
    val job = launch {
        delay(2000)
        println("job is finished")
    }
    println("foo continues")
    job.join()
    println("foo is finished")
}

would result in

foo continues
job is finished
foo is finished
