Arguments: window &key owner-p
In release 6.0 and later, use of this function is deprecated in favor
of child-p (which
returns the opposite of what this function returns, so replace calls
to top-level with (null (child-p ...))). This
function is maintained for backward compatibility.
Release 6.0 non-backward-compatible change: the stop-at-modal keyword argument has been removed. It in fact had no effect (since all modal dialogs are top-level window so this function always returned true for them).
Here is the pre-6.0 description of this function, somewhat edited:
If owner-p is nil, returns
true if window is a top-level window and nil otherwise. A top-level window is one whose parent
is the screen, though it may have an owner window. If owner-p is
true, returns true if window
has no owner window, and nil if it does have
an owner window.
If stop-at-modal [starting in release 6.0, no longer accepted, this description kept for reference only] is true and window is a pop-up window, then true will always be returned; otherwise the return value is as described above.
