How to call a suspend function from a standard function within coroutines?

To call a suspend function from a regular (non-suspend) function, you need to launch a coroutine, as suspend functions can only be executed within a coroutine context. You can use runBlocking (if you need blocking execution) or create a coroutine using CoroutineScope.launch or CoroutineScope.async.

Example with runBlocking:

fun standardFunction() {
    runBlocking {
        suspendFunction()
    }
}

suspend fun suspendFunction() {
    println("Executing suspend function")
}

If you do not want to block the thread, it is better to use CoroutineScope.launch:

fun standardFunction() {
    val scope = CoroutineScope(Dispatchers.Default)
    scope.launch {
        suspendFunction()
    }
}

Thus, calling a suspend function from a regular function is only possible within a coroutine.
