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".
