Alternatively, you can pass around the SEL type that you get when you
use M(methodName).  Call a SEL with perform:.  Functions will be somewhat
faster.

typedef void (*func_t) (int count, const char **strings);

void
print_strings (int count, const char **strings)
{
  int i;

  printf ("count: %u\n", count);

  for (i = 0; i < count; i++)
    printf ("string[%u]: `%s'\n", i, strings[i]);
}

void
call_func (func_t func, int count, const char **strings)
{
  func (count, strings);
}

int
main (int argc, const char **argv)
{
  call_func (print_strings, argc, argv);
}

/*
Local Variables:
compile-command: "gcc callfunc.c -o callfunc"
End:
