PerlIO::mmap(3p) | Perl Programmers Reference Guide | PerlIO::mmap(3p)

# 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;".
