If I’m writing a C extension, how would I go about calling “Signal.list”  
from  
within that extension?

I would normally do something like this:

rb\_funcall(rb\_mSignal, rb\_intern(“list”), 0);

But there doesn’t seem to be an rb\_mSignal object available.

VALUE xx\_mSignal;

xx\_mSignal = rb\_const\_get(rb\_cObject, rb\_intern(“Signal”));

/\* … \*/

rb\_funcall(xx\_mSignal, rb\_intern(“list”), 0);
