They are actually macros. ndarrayobject.h:#define PyArray_SimpleNew(nd, dims, typenum) \ ndarrayobject.h- PyArray_New(&PyArray_Type, nd, dims, typenum, NULL, NULL, 0, 0, NULL) ndarrayobject.h- ndarrayobject.h:#define PyArray_SimpleNewFromData(nd, dims, typenum, data) \ ndarrayobject.h- PyArray_New(&PyArray_Type, nd, dims, typenum, NULL, \ ndarrayobject.h- data, 0, NPY_CARRAY, NULL) ndarrayobject.h- ndarrayobject.h:#define PyArray_SimpleNewFromDescr(nd, dims, descr) \ ndarrayobject.h- PyArray_NewFromDescr(&PyArray_Type, descr, nd, dims, \ ndarrayobject.h- NULL, NULL, 0, NULL) The main change is that dims needs to point to npy_intp instead of int so that 64 bit architectures can use large arrays. I'm not sure the recommended replacements are the best, I just copied them from comments in the source code. Travis could perhaps clarify things a bit for us. Chuck
