Coroutine.yield
From GiderosMobile
Available since: Gideros 2011.6
Class: coroutine
Description
Suspends execution of the coroutine.
(any) = coroutine.yield(...)
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
Any arguments to yield are passed as extra results to resume. Yielding a coroutine inside metamethods or C functions is prohibited, with the exception of pcall and xpcall
Parameters
...: (any) values to return from coroutine.resume call optional
Return values
Returns (any) values to return if any
