Subject: Invoking method with a block in C extension

Hi.
I'm converting some of my ruby code to C extension for better perfomance. 
I ran into problems with executing methods that take blocks.
I.e. in ruby i have 
	string.gsub!(/regexp/) { |subst| ... }
and i can't find the way to translate it to C. I tried to search through 
ruby-talk archives, but I couldn't find anything usefull.
As far as I was looking at problem, I found rb_iterate, rb_yield, but I 
couldn't clearly understand what's their purpose, and how to get them all 
together to achieve what I want.
Could somebody please explain me how can I implement this ruby code in C?
I'd really appreciate any help. Thanks in advance!
