Hi,

Is this API supported by ruby 1.9, I’m trying module to load pre-  
compiled version of a script but I endup with core dump.

this the extension:

#include \<ruby.h\>

VALUE Loader = Qnil;

VALUE load\_ruby\_iseq(int argc, VALUE \*argv, VALUE self)  
{  
VALUE data, opt=Qnil;  
rb\_scan\_args(argc, argv, “11”, &data, &opt);

return rb\_iseq\_load(data, 0, opt);  
}

void Init\_loader()  
{  
Loader = rb\_define\_class(“Loader”, rb\_cObject);  
rb\_define\_singleton\_method(Loader, “load”, load\_ruby\_iseq, -1);  
}

This the first time i wrote ruby extension, so I’m guessing something  
wrong with my code !!!

Thanks  
Husam

> return rb\_iseq\_load(data, 0, opt);

twould appear that that’s the right way.

maybe ask core about it?
