   Subject: more etags torture;-) [etags 7.3 patch#3]
   To: pot@CNUCE.CNR.IT

   Hi,

   This test file illustrates some more problems with etags (7.3):
 

   1. parentheses are confusing,
   2. preprocessor directives can disrupt other state machines. */

/* A small torture test for etags. */

/* The classic parenthesis nightmare, based on signal(). */
void
(*tag1 (sig, handler)) ()
  int sig;
  void (*handler) ();
{
  (*handler)(sig);
  return handler;
}

#define notag2 void
/* The classic, with user-defined return type. */
notag2
(*tag2 (sig, handler)) ()
  int sig;
  void (*handler) ();
{
  (*handler)(sig);
  return handler;
}

/* The classic, in ANSI C style. */
void
(*tag3 (int sig, void (*handler) (int))) (int)
{
  (*handler)(sig);
  return handler;
}

#define notag4 void
/* The classic, with user-defined return type, in ANSI C style. */
notag4
(*tag4 (int sig, void (*handler) (int))) (int)
{
  (*handler)(sig);
  return handler;
}


/* A less tortuous example. */
void
tag5 (handler, arg)
void (*handler)();
void *arg;
{
  (*handler)(arg);
}

/* A less tortuous example, in ANSI C style. */
void
tag6 (void (*handler) (void *), void *arg)
{
  (*handler)(arg);
}
