fyi, exactly what I did was this
my $type;
%results = findResults(\$type);
$type is then modified inside findResults() but only the hash is passed back to the caller. So the value of $type is changed but never passed back,so as to avoid slurpage
Is this ok style? or is that a little too C++?
You can return only a scalar or a list from a function. To get a hash return, you either have to flatten it into a list (and reconstruct it at the other side) or return a reference to the hash
I haven't found this to be so, unless perl is taking care of the reconstruction for me. I returned a hash like so return %results; and the calling hash was populated correctly. I was able to do a foreach over each of the keys i had set. Perl is taking care of the reconstruction correct?
