 Reads or writes C<$length> bytes from or to the specified C<$fh> and
 C<$offset> into the scalar given by C<$data> and offset C<$dataoffset>
 and calls the callback without the actual number of bytes read (or -1 on
 error, just like the syscall).
+C<aio_read> will, like C<sysread>, shrink or grow the C<$data> scalar to
+offset plus the actual number of bytes read.
 If C<$offset> is undefined, then the current file descriptor offset will
 be used (and updated), otherwise the file descriptor offset will not be
 changed by these calls.
