Description

In order for multiple coroutines to share execution they must stop executing (after performing a sensible amount of processing) and pass control to another thread. This act of submission is called yielding. Coroutines explicitly call a Lua function coroutine.yield(), which is similar to using return in functions. What differentiates yielding from function returns is that at a later point we can reenter the thread and carry on where we left off. When you exit a function scope using return the scope is destroyed and we cannot reenter it, e.g.,

= coroutine.yield(val1...,)

val1: (any) value to return from coroutine.resume call optional
...: (multiple) other optional values that will be returned from coroutine.resume call optional
