File Handles as arguments...

[Mike Breeze]

Hi all,

Firstly, this a great list. Thanks to those responsible for coming up
with it and supporting it.

I'm writing some subroutines that will require a filehandle to be passed
in. I've been looking at a FAQ on perl.com
(http://www.perl.com/pub/doc/FAQs/FAQ/oldfaq-html/Q5.25.html), which
suggested the two following options:

CODE 3:

    printit(*Some_Handle);
    sub printit {
        my $fh = shift;
        while (<$fh>) {
            print;
        }
    }


CODE 4:

    printit(\*Some_Handle);
    sub printit {
        my $fh = shift;
        while (<$fh>) {
            print;
        }
    }

Is one better/safer/more robust than the other? My gut feeling is to go
for the latter but I'm not really sure why.

Cheers

Mike
