=head1 NAME
|
||
|
|
||
|
PerlIO::mmap - Memory mapped IO
|
||
|
|
||
|
=head1 SYNOPSIS
|
||
|
|
||
|
open my $fh, '<:mmap', $filename;
|
||
|
|
||
|
=head1 DESCRIPTION
|
||
|
|
||
|
This layer does C<read> and C<write> operations by mmap()ing the file if possible, but falls back to the default behavior if not.
|
||
|
|
||
|
=head1 IMPLEMENTATION NOTE
|
||
|
|
||
|
C<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 C<use PerlIO::mmap;>.
