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;".
