So, Im trying to move away from mkmf, and onto RubyInline.  
I can’t work out how to define alloc functions from Inline, I tried  
something like:

class Y  
inline :C do |builder|  
builder.c \<\<-ENC  
void Init\_Y(){

```
  }
ENC

```

end  
end

but that makes Init\_Y a instance method, and I’m unsure of how to get  
the  
klass.

Has anyone done this before?

Thanks,  
Joey

this says you are in a class.

Don’t do this, define initialize instead. If you need to add things  
to the Init method, use the hook for it (I forget what it is called).
