NAME

PerlIO::mmap - Memory mapped IO

SYNOPSIS

 open my $fh, '<:mmap', $filename;

DESCRIPTION

This layer does read and write operations by mmap()ing the file if possible, but falls back to the default behavior if not.

IMPLEMENTATION NOTE

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 use PerlIO::mmap;.
