Couldn't get your code, or ikegami's to work for me ... not sure why. (Update: Nothing wrong with ikegami's code, of course. Looks to me that $value in the op's code bears no relation to the hashref that has been returned and therefore is undef.)

The following *does* work for me, and should contain all you need to get your own code working: 
use Inline C => Config =>
    BUILD_NOISY => 1;

use Inline C;
      
    $arref = get_data();
    
    print $arref, "\n";

    print $arref->[0]->{mickey}, "\n";
    print $arref->[0]->{donkey}, "\n";


__END__
__C__

 SV* get_data() {
    AV * results;
    HV * rh = newHV();

    results = newAV();

    hv_store(rh, "mickey", 6, newSVpv("mouse", 0), 0);
    hv_store(rh, "donkey", 6, newSVpv("kong", 0), 0);
 
    av_push(results,newRV_noinc((SV*)rh));

    return newRV_noinc((SV*)results);

}

Update: The 'BUILD_NOISY' config option that I've included in the above script ensures that you get the opportunity to see compiler warnings - which can be useful if a script does not behave as intended. It's a good idea to *always* have BUILD_NOISY switched on.

Cheers,
Rob
