I have an embedded Perl app where I generate a hash reference in perl and pass this back to C. If I print the hex address in both Perl and C, I get the same number.

I don't intend to use the pointer in C, just pass it around as an opaque pointer.

My question is how to get this void * from C back into Perl so that I can access the contents of this hash reference. Now I can push simple stuff onto the stack, but what I need to be able to do is push this hash reference address on the stack such that when I call this Perl code via call_pv, I can access this perl function (for instance): 

sub foo {
  my ($href, $key) = @_;
  print $href->{$key};
}
Thanks a bunch. This is a hard one to google for... WGIII
