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 $fh, ">>:scalar", \$scalar or die;
DESCRIPTION
A filehandle is opened but the file operations are performed
"in-memory" on a scalar variable. All the normal file
operations can be performed on the handle. The scalar is
considered a stream of bytes. Currently fileno($fh) returns
"undef".
IMPLEMENTATION NOTE
"PerlIO::scalar" only exists to use XSLoader to load C code
that provides support for treating a scalar as an "in
memory" file. One does not need to explicitly "use
PerlIO::scalar".
