Prevents the menu from being closed when the user selects from another menu, if this function is defined as the exit action for a menu. Use this function if you want the user to take some definite action before leaving the current menu.

This function affects Menu-Manager (mode-specific) menus only.

To use this function, you must ensure that at least one of the buttons on the menu results in a call to either ProMenuDelete() or ProMenuDeleteWithStatus(). Otherwise, there will be no route out of the menu.
