Subject: 'C' based iterators

Fellow Rubyists,
Been cracking my skull on how to code iterators in 'C', and need a few
pointers:

1. rb_iter_break() is the equvalent of "break", what is the equivalent
of "next"?

2. Scoping tricks
<ruby code>
bar = nil
foo.each { |bar|
   next if bar.capacity < size
   break
}       
</ruby>

In Ruby, I can do scoping tricks as above, so that I get the value of
bar if the test fails outside of the block. How the heck can I do that
in 'C'?

TIA.
