PerlIO::mmap(3pm) Perl Programmers Reference Guide PerlIO::mmap(3pm)
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;".
