Subject: getting a method from a block in C

 
Hello! 
 
Suppose I have some ruby code: 
 
def bar 
	puts "Hello" 
end 
 
foo { bar } 
 
Now, foo is part of a Ruby extension, but bar is user implemented. 
The C implementation of foo can use rb_block_given_p() to identify if 
it was called with a block. My question is: can I grab the bar method, save 
its pointer somewhere and call it from other places in my code? I.e. is 
there an option in the Ruby C API to parse/identify args in a given block? 
 
I don't want to yield bar, just save it and call it later (foo is actually a C++ 
constructor, which takes as an argument a pointer to a user function). 
 
  
Regards,
