The function header looks like this:

SWIGINTERN PyObject *_wrap_G_vasprintf(PyObject *SWIGUNUSEDPARM(self),
PyObject *args) {
  PyObject *resultobj = 0;
  char **arg1 = (char **) 0 ;
  char *arg2 = (char *) 0 ;
  va_list arg3 ;                       <<<----
  void *argp1 = 0 ;
  int res1 = 0 ;
  int res2 ;
  char *buf2 = 0 ;
  int alloc2 = 0 ;
  void *argp3 ;
  int res3 = 0 ;
  PyObject * obj0 = 0 ;
  PyObject * obj1 = 0 ;
  PyObject * obj2 = 0 ;
  int result;
