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".
