NAME

6       PerlIO::mmap - Memory mapped IO
7

SYNOPSIS

9        open my $fh, '<:mmap', $filename;
10

DESCRIPTION

12       This layer does "read" and "write" operations by mmap()ing the file if
13       possible, but falls back to the default behavior if not.
14

IMPLEMENTATION NOTE

16       "PerlIO::mmap" only exists to use XSLoader to load C code that provides
17       support for using memory mapped IO. One does not need to explicitly
18       "use PerlIO::mmap;".
