This question would be more appropriate for the gcc-h...@gcc.gnu.org mailing list. The answer is no: you can not pass va_list values between threads. If you think about it you will realize that the va_list value can not hold the complete set of variable arguments, as there is no way to know how many there are. Therefore, if you pass enough variable arguments to a function, it is guaranteed that some will be on the stack. You can not reliably pass a reference to the stack of one thread to another thread, because the first thread might exit before the second thread runs. Ian
