 and sets errno to C<ENOSYS>.
 Note that the corresponding C<munlock> is synchronous and is
 documented under L<MISCELLANEOUS FUNCTIONS>.
+Example: open a file, mmap and mlock it - both will be undone when
+C<$data> gets destroyed.
+   open my $fh, "<", $path or die "$path: $!";
+   my $data;
+   IO::AIO::mmap $data, -s $fh, IO::AIO::PROT_READ, IO::AIO::MAP_SHARED, $fh;
+   aio_mlock $data; # mlock in background
 =item aio_mlockall $flags, $callback->($status)
 Calls the C<mlockall> function with the given C<$flags> (a combination of
 C<IO::AIO::MCL_CURRENT> and C<IO::AIO::MCL_FUTURE>).
 On systems that do not implement C<mlockall>, this function returns C<-1>
 and sets errno to C<ENOSYS>.
 Note that the corresponding C<munlockall> is synchronous and is
 documented under L<MISCELLANEOUS FUNCTIONS>.
+Example: asynchronously lock all current and future pages into memory.
+   aio_mlockall IO::AIO::MCL_FUTURE;
 =item aio_group $callback->(...)
 This is a very special aio request: Instead of doing something, it is a
 container for other aio requests, which is useful if you want to bundle
