5.12: How can I open a filehandle to a string?
(contributed by Peter J. Holzer, hjp-usenet2@hjp.at)
Since Perl 5.8.0 a file handle referring to a string can be created by
calling open with a reference to that string instead of the filename.
This file handle can then be used to read from or write to the string:
open(my $fh, '>', $string) or die "Could not open string for
writing";
print $fh "foo\n";
print $fh "bar\n"; # $string now contains "foo\nbar\n"
open(my $fh, '<', $string) or die "Could not open string for
reading";
my $x = <$fh>; # $x now contains "foo\n"
With older versions of Perl, the "IO::String" module provides similar
functionality.

The perlfaq-workers, a group of volunteers, maintain the perlfaq. They
are not necessarily experts in every domain where Perl might show up,
so please include as much information as possible and relevant in any
corrections. The perlfaq-workers also don't have access to every
operating system or platform, so please include relevant details for
corrections to examples that do not work on particular platforms.
Working code is greatly appreciated.
