I might be wrong here, but I think that with all compilers that I know about that code should work. The compiler will complain about the type mismatch but if you do not access the arguments you should be able to have them on the stack with any issue. Of course your example is a lot more correct (and actually useful!) but the code above should basically work, although I didn’t try it. _______________________________________________ Discuss-gnustep mailing list [email protected] https://lists.gnu.org/mailman/listinfo/discuss-gnustep
