NAME
       PerlIO::scalar - in-memory IO, scalar IO

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 -1.

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".
