Hi,
You should read the perllol documentation. It has got lots of information
about what you're talking about. This isn't a mod_per specific issue.
First of all:
the subhash you are referring to is just a value of the
%Action::Vars::config has. So you retrieve it like this:
$hashref = $Actions::Vars::config{$conf}
Now, that gives you a hash reference, from which you can access values
using $hashref->{key} ou $$hashref{key}.
If you want to retrieve the hash in normal form, like this:
my %conf = get_conf($conf);
You need to access all the values of the sub-hash.
So you get:
return %{$Actions::Vars::config{$conf}};
and then you can do:
my %hash = get_conf($conf); (or whatever)
This is actualle equivalent to:
my $hashref = $Actions::Vars::config{$conf};
my %hash = %$hashref;
Again, see perllol, it'll give you insight into this matter.
