package PerlIO::mmap; use strict; use warnings; our $VERSION = '0.017'; use XSLoader; XSLoader::load(__PACKAGE__, __PACKAGE__->VERSION); 1; __END__ =head1 NAME PerlIO::mmap - Memory mapped IO =head1 SYNOPSIS open my $fh, '<:mmap', $filename; =head1 DESCRIPTION This layer does C<read> and C<write> operations by mmap()ing the file if possible, but falls back to the default behavior if not. =head1 IMPLEMENTATION NOTE C<PerlIO::mmap> only exists to use XSLoader to load C code that provides support for using memory mapped IO. One does not need to explicitly C<use PerlIO::mmap;>. =cut
