Use
IO::Scalar for this.
#!/usr/bin/perl
use strict;
use warnings;
use IO::Scalar;
my $data = 'some sample data here';
my $fh = IO::Scalar->new(\$data);
print {*STDERR} 'ref $fh yields ', ref $fh, "\n";
print_prop('$fh->can("opened")', $fh->can('opened'));
print_prop('$fh->can("seek")', $fh->can('opened'));
print_prop('$fh->can("seekable")', $fh->can('opened'));
print_prop('$fh is IO::Scalar', $fh->isa('IO::Scalar'));
print_prop('$fh->can("opened")', $fh->can("opened"));
print_prop('$fh->opened()', $fh->opened());
print_prop('$fh->can("seek")', $fh->can("seek"));
eval {print_prop('$fh->seek(0, 0)', $fh->seek(0, 0));} or print "$@";
print_prop('$fh is tied', tied $fh);
close $fh;
sub print_prop {
my ($msg, $flag) = @_;
print {*STDERR} $msg, '? ', ($flag ? 'yes' : 'no'), "\n";
return;
}
which yields
ref $fh yields IO::Scalar
$fh->can("opened")? yes
$fh->can("seek")? yes
$fh->can("seekable")? yes
$fh is IO::Scalar? yes
$fh->can("opened")? yes
$fh->opened()? yes
$fh->can("seek")? yes
$fh->seek(0, 0)? yes
$fh is tied? no

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
