PerlIO::mmap(3perl)              Perl Programmers Reference Guide             PerlIO::mmap(3perl)

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;".
