Ns_format_function

What would be a good equivalent of this objc in Oxygene ?

  • (void)logMessage:(NSString *)format, … NS_FORMAT_FUNCTION(1,2) {
    // gets message as string
    va_list argp;
    va_start(argp, format);
    NSString *log = [[NSString alloc] initWithFormat:format arguments:argp];
    va_end(argp);

    // outputs to stdout
    NSLog(@"%@", log);

    }

I figured I could just copy the declaration for NSLog but the compiler complains about not being able to find

&Var

Thanks,
John

Elements currently does not support defining va_list methods.
