Well, here is one example where you don't want the '\0' appended onto the end:

---- snip ----
voir example (void)
{
  static char buf[100];
  ostrstream ostr(buf, 100);

  for (int i = 0; i < 100; i++) ostr << 'a';

  char *str = ostr.str();  // Certainly don't want to append a '\0', since buf[] already has 100 chars in it!
}
--- snip ---
