 Call the callback when a status change for pid C<$pid> (or any pid
 if C<$pid> is 0) has been received. More precisely: when the process
 receives a SIGCHLD, EV will fetch the outstanding exit/wait status for all
 changed/zombie children and call the callback.
-Unlike all other callbacks, this callback will be called with an
+You can access both status and pid by using the C<rstatus> and C<rpid>
-additional third argument which is the exit status. See the C<waitpid>
+methods on the watcher object.
-function for details.
 You can have as many pid watchers per pid as you want.
 The C<child_ns> variant doesn't start (activate) the newly created watcher.
 =item $current_pid = $w->pid
 =item $old_pid = $w->pid ($new_pid)
 Returns the previously set process id and optionally set a new one.
+=item $exit_status = $w->rstatus
+Return the exit/wait status (as returned by waitpid, see the waitpid entry
+in perlfunc).
+=item $pid = $w->rpid
+Return the pid of the awaited child (useful when you have installed a
+watcher for all pids).
