that isn’t the case apparently.

That kind of defeats the purpose then if you can’t rely on function scoped
variables to be restored. Maybe that’s what the code in the

I was curious about possible ways coroutines could work in FPC and found this
example that claims to implement just that. It appears to be designed for
Windows though and makes use of a function called VirtualAlloc which I don’t
understand. Is there a non platform specific version of this functi
