int acedRetVoid();

Description
Returns a blank value (void, which is not displayed) to AutoLISP. The AutoLISP expression that invoked the external function does not print a result. This is useful in external functions defined as AutoCAD C: commands. (Calling acedRetVoid() is similar to using the AutoLISP function (princ) to suppress the printing of a return value.)
An external function can make more than one call to value-return functions upon a single kInvkSubrMsg message, but the AutoLISP function returns only the value passed it by the last value-return function invoked.
The acedRetVoid() function always returns RTNORM.
