Fredrik,
...I tried using your code...
static long *get_long_array(PyObject *data, int *data_size) {
int i, size;
long* out;
PyObject* seq;
seq = PySequence_Fast(data, expected a sequence);
if (!seq)
return NULL;
size = PySequence_Size(seq);
if (size 0)
I got it. I had get_long_array placed after the method that was
calling it..
i.e.
void doStuf(...) {
x = get_long_array(...);
}
static long *get_long_array(PyObject *data, int *data_size) {
...
}
...I put get_long_array before it in my code..and its fine.
Thanks

what other warnings did you get from the compiler?

eh? if you're not sure, what keeps you from
I have a C function which takes an array of long values..
I understand that I can pass a tuple to a C wrapper function and in the
C wrapper function have..
int ok = PyArg_ParseTuple(args, s(ll), a, b, c);
..that's great if my tuple only contained two longs..but what if it
contained 50

It depends on how you want to manipulate the data in C. If you want
compile-time variable access to each float, yeah, 50 floats. :)
Probably what you want to do though is just keep the tuple as is and
iterate over it using the PySequence_* protocol:
