Subject: GC and the stack

Hello,

As far as I understand the ruby gc will not collect objects that are
referenced from the stack, ie the "C/native" stack in a ruby extension
module.

How does the ruby gc recognize what on the stack is a reference to a ruby
object? The types on and layout of the values in a particular stack frame is
not available at runtime is it?

The initial joy of the simplicity of the ruby C API has for me turned into a
fear of not knowing what is going on concerning especially garbage
collection.
