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
     "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".
