[Numpy-discussion] use of the PyArray_SETITEM numpy method

Hello, Please somebody help me ! I am really confused with all these void that I see everywhere. The documentation says: PyObject * PyArray_SETITEM(PyObject * arr, void* itemptr, PyObject* obj) I created a 1D array of doubles with PyArray_SimpleNew. Now I am in a loop of index i to feed my array with values. What should I give for itemptr ? Thank you
