 C<IO::AIO::MAP_NORESERVE>, C<IO::AIO::MAP_POPULATE> or
 C<IO::AIO::MAP_NONBLOCK>
 If C<$fh> is C<undef>, then a file descriptor of C<-1> is passed.
+C<$offset> is the offset from the start of the file - it generally must be
+a multiple of C<IO::AIO::PAGESIZE> and defaults to C<0>.
+Example:
+   use Digest::MD5;
+   use IO::AIO;
+   open my $fh, "<verybigfile"
+      or die "$!";
+   IO::AIO::mmap my $data, -s $fh, IO::AIO::PROT_READ, IO::AIO::MAP_SHARED, $fh
+      or die "verybigfile: $!";
+   my $fast_md5 = md5 $data;
 =item IO::AIO::munmap $scalar
 Removes a previous mmap and undefines the C<$scalar>.
 =item IO::AIO::mlockall $flags
