Hi Madan,

Thanks for the tip. Unfortunately that technique won't work in this specific case. Namely its a Format() style function that's called all over the place and replacing all those calls isn't possible.

I actually ended up modifying the format string, and using CFStringCreateWithFormatAndArguments() to do all the heavy lifting. It does what the function was trying to do in the first place (create a string from a format string that might have order specifiers).

Hi,
I ran into the same trouble with Fireworks Codebase. I workaround this by
passing ptrs instead of the objects.
My problem was little typical because I was supposed to pass class objects.
Passing simple POD-types through va_arg list works but when we try to pass
our class objects in va_lists it would fail,so would prefer passing pts.


Thanks
Madan

Hi all,

I'm converting a project from CodeWarrior to Xcode 2.2/gcc 4. I've
run into some code that attempts reorder a variable argument list
(for localized string formatting). The basic code is:

va_start(argList, format);

int foo = 4;
va_arg(argList, int) = foo;

gcc doesn't like the last line because va_arg doesn't return an lval.
Specifcally its says "invalid lvalue in assignment".  Apparently
CodeWarrior va_arg returned a reference, which gcc doesn't.

Is there any way to modify a va_list, either in place or build one up
dynamically?

Thanks,

     -andy
