=head1 SYNOPSIS
|
|
|
|
my $scalar = '';
|
|
...
|
|
open my $fh, "<", \$scalar or die;
|
|
open my $fh, ">", \$scalar or die;
|
|
open my $fh, ">>", \$scalar or die;
|
|
|
|
or
|
|
|
|
my $scalar = '';
|
|
...
|
|
open my $fh, "<:scalar", \$scalar or die;

open my $fh, ">:scalar", \$scalar or die;
|
|
open my $fh, ">>:scalar", \$scalar or die;

|
=head1 DESCRIPTION
|
|
|
|
A filehandle is opened but the file operations are performed "in-memory"
|
|
on a scalar variable. All the normal file operations can be performed
|
|
on the handle. The scalar is considered a stream of bytes. Currently
|
|
fileno($fh) returns -1.
|
|
|
|
Attempting to open a read-only scalar for writing will fail, and if
|
|
warnings are enabled, produce a warning.
|

|
=head1 IMPLEMENTATION NOTE
|
|
|
|
C<PerlIO::scalar> only exists as a stub. One does not need to explicitly
|
|
C<use PerlIO::scalar>.
