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

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,
