Subject: Methods written in C and code blocks

It there a way to pass code block to method, written in C?

What I want is something like

require 'myext'
include Myext

Myclass.mymeth(56) do |x|
   p x
end
---------------------------------------------------
myext.c
...
void Init_myext()
{
   VALUE m =  rb_define_module("Myext");
   rb_define_module_function(m, "mymeth", mymeth, 1); /* ? */
}
...

VALUE mymeth() /* ? */

How can I define mymeth and yield block inside of it?
