[Python] Is there any problem using deprecated NumPy API?

I want to pass numpy array to c++, but there is a deprecated numpy API and I don't know where to find the substitute. It shows me a warning message when I build my c++ code to make library.

numpy\npy_1_7_deprecated_api.h(14) : Warning Msg: Using deprecated NumPy API, disable it with #define NPY_NO_DEPRECATED_API NPY_1_7_API_VERSION

Is there any problem to use deprecated API? If I use it, it runs only once and just quit my program without any further error/warning message(this cfunc should run many times in a loop in my python code that imports c library.). Of course if I disabled deprecated API, it just tells me that it cannot find that API.

Here is a part of my code to receive numpy array and convert it to double array to handle it in c++

#include <Python.h>
#include "numpy\ndarraytypes.h"
#include "numpy\ndarrayobject.h"
#include "numpy\arrayobject.h"

static PyObject* cfunc(PyObject* self, PyObject* args)
{
PyArrayObject* numpyarray;
double* carray;

if (!PyArg_ParseTuple(args, "O", &numpyarray))
{
return NULL;
}
carray = (double*)numpyarray->data; // When I build this code, it says 'data' is not a member of 'tagPyArrayObject'


Please let me know if you have any idea.

Thank you so much!

Best wishes, JESuh
