  It's actually pretty straightforward:
  
  #include <stdio.h>
  #include <stdarg.h>
  
  void bar(int cnt, ...) {
      va_list ap;
      va_start(ap,cnt);
      while (cnt--) {
          int a = va_arg(ap, int);
          printf("%d ", a);
      }
      printf("\n");
  }
  
  int main() {
      void (*b)(int, ...);
      b = bar;
      b(2,1,2);
      b(3,1,2,3);
      return 0;
  }
  
  Or did I miss something?

    Hmm, no. I missed b = bar; in my example, which leads me to wonder why there was no crash.

    Thanks for the sanity check! Now I need to figure out how to add varargs support to NCI.
