Since engine version: 1.0 OC
Returns the id of the menu if the object has an open menu. This is usually the id of the menu symbol (symbol) unless CreateMenu was used to explicitly use a differing menu id in idMenuID.
A return value of
nilmeans that no valid symbol could be determined. This may happen e.g. if no object pointer was passed during a global call to the function. Engine defined menus such as Buy, Sell, etc. never return valid ids.
