package PerlIO::scalar; our $VERSION = '0.26'; require XSLoader; XSLoader::load(); 1; __END__ =head1 NAME PerlIO::scalar - in-memory IO, scalar IO =head1 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 $fh, ">>:scalar", \$scalar or die; =head1 DESCRIPTION A filehandle is opened but the file operations are performed "in-memory" on a scalar variable. All the normal file operations can be performed on the handle. The scalar is considered a stream of bytes. Currently fileno($fh) returns -1. =head1 IMPLEMENTATION NOTE C<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 C<use PerlIO::scalar>. =cut
