get-position

Arguments: window-or-screen &optional scroll-p cursor

Waits until the user presses a mouse button down, and then returns the current position of the mouse cursor in the stream coordinates of window-or-screen. The screen is the value returned by (screen *system*). See screen and *system*.

If scroll-p is true, the window (identified by window-or-screen) will be scrolled if the cursor moves outside it. Sets the stream cursor to cursor while running. If the cursor argument is t, a default is used (typically the cross-hair cursor).

You may wish to call wait-for-mouse-buttons-up prior to calling get-position to ensure that mouse button releases associated with other actions do not interfere with getting the desired position.
