Here is the definition of that call from ndarrayobject.h
#define PyArray_DIMS(obj) (((PyArrayObject *)(obj))->dimensions)
I believe the memory has been allocated. It just return a pointer.

Hi!
I have problem with this function call under FC6 X86_64 for my own
numpy extension
printf("\n %d %d %d", PyArray_DIM(imgi,0),PyArray_DIM(imgi,
1),PyArray_DIM(imgi,2))
it gave me
166 256 256
if I tried:
int *dim;
dim = PyArray_DIMS(imgi)
printf("\n %d %d %d", dim[0], dim[1], dim[2]);
it gave me 166 0 256
Hi -
maybe I'm dense here -
but how is this /supposed/ to work ? Is PyArray_DIMS allocating
some memory that never gets freed !?
I thought "tuples" in C had to always be passed into a function,
so that that function could modify it, as in:
const int maxNDim = 20;
int dim[maxNDim];
PyArray_DIMS(imgi, dim);
What am I missing ... ?
