[Numpy-discussion] quick C api array creation question

Hi,

I'm using a C api to create numpy array

I create them in my C as follow:

   np_ow = (PyArrayObject *)PyArray_SimpleNew(4, dims, NPY_DOUBLE);
   np_osfc = (PyArrayObject *)PyArray_SimpleNew(3, dims, NPY_DOUBLE);
   np_ospc = (PyArrayObject *)PyArray_SimpleNew(3, dims, NPY_DOUBLE);
   PyArray_FILLWBYTE(np_ow,0);
   PyArray_FILLWBYTE(np_osfc,0);
   PyArray_FILLWBYTE(np_ospc,0);
...
   return Py_BuildValue("OOO",np_ow,np_osfc,np_ospc);

It seems to work and they get back nicely to the python, no problem

The only "little" issue I have is that the memory is never released!  
And quickly my code runs out of memory

Any pointer on what I'm doing wrong?

Do I need a decref somewhere?

C.
