M> Look at this script:
OK... Thank you for the Perl example. I've just begun to learn the
language... I have a question that no doubt I can answer on my own
after actually readin ALL of the perl manuals (I have the `info'
version, and have read part of it, and all of the camel book, as well
as some of a few other books on Perl...)...
Why must you call `print_du' like that... Let's see. The "('Size
Data' => $data)" constructs a reference to a hash with one key, "Size
Data". Why can't you just do something more like:
my $data = &check_du();
&print_du($data);
... then in &print_du, assign `my %params' as `my $data = $_[1]'?
I'll go ahead and mail this anyway, then hit the info's.
sub print_du {
my %params = @_;
croak("Need argument 'Size Data'") unless defined $params{'Size Data'};
for (sort keys %{$params{'Size Data'}}) {
next unless $params{'Size Data'}{$_}{'Size'};
printf "%10d %s\n", $params{'Size Data'}{$_}{'Size'},
$params{'Size Data'}{$_}{'Name'};
}
}
sub test_du {
my $data = &check_du();
&print_du('Size Data' => $data);
}
