C Extension - return an array of longs or pointer?

[Brandon K]

I'm sorry...I just woke up and forgot my C...must have left it in the 
Coffee...Anyway, i made a few mistakes (can't initialize blank 
tuple...function should return a value, lol).

static PyObject* wrap_doNumberStuff(PyObject* self, PyObject* args)
{
	char* in = 0;
	char* x = 0;
	long* result = 0;
	int i = 0;
	PyObject* py = NULL;
	if(!PyArg_ParseTuple(args,"ss",&in,&x) return NULL;
	
	result = doNumberStuff(in,x);
	len = sizeof(result)/sizeof(long);
	py = PyTuple_New(len);
	for(i; i < len; i++)
		PyTuple_SET_ITEM(py, i, Py_BuildValue("l",*result[i]);

	return py;
}

Additionally, the Python/C api in the docs tells you all of these nifty 
little abstract layer functions that you can call from your extension.
