 Well, this is very quickly written

pigeon% cat a.c
#include <ruby.h>

static VALUE 
aa_func(obj)
    VALUE obj;
{
    rb_p(rb_str_new2("I'm is ruby_func"));
    return obj;
}

int main()
{
    ruby_init();
    ruby_init_loadpath();
    rb_define_method(rb_cObject, "ruby_func", aa_func, 0);
    rb_p(rb_str_new2("before b.rb"));
    rb_load_protect(rb_str_new2("b.rb"), Qfalse, 0);
    rb_p(rb_str_new2("after b.rb"));
}
pigeon% 

pigeon% cat b.rb
#!/usr/bin/ruby
p "before ruby_func"
ruby_func
p "after ruby_func"
pigeon%
 
pigeon% a.out
"before b.rb"
"before ruby_func"
"I'm is ruby_func"
"after ruby_func"
"after b.rb"
pigeon%
