[Omaha.pm] Accessing CGI objects passed through a function call...

[Dan Linder <dan@linder.org>]

I'm trying to access the Perl CGI modules self_url call in a function
call.  Here's my code:

=== test001.pl ===
#!/usr/bin/perl
use lib ".";
use CGI;
use MyModule;
my $cgi = CGI->new();

show_my_link(\$cgi);
exit;
=== end test001.pl ===

My module is like this:
=== MyModule.pm ===
package MyModule;
use Exporter;
@ISA = qw(Exporter);
@EXPORT = qw(show_my_link);

sub show_my_link {
    my ($thecgi) = @_;
    printf ("The full URL is: %s\n", $thecgi->self_url());
}
1;
=== end MyModule.pm ===

When I run the code above, I get the error:
    Can't call method "self_url" on unblessed reference at MyModule.pm line 8.
(Line 8 is the printf...self_url line.)

I think I'm close, but is there something else I'm missing to make this call?

Thanks in advance!

Dan
