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;".
