[Numpy-discussion] C Api newbie question

[Matt K. <mat...@ho...>]

Hi there. I'm in the unfortunate situation of trying to track down a memory=
 error in someone elses code, and to make matters worse I don't really know=
 jack squat about C programming. The problem seems to arise when several nu=
mpy arrays are created from C arrays in the C api and returned to python, a=
nd then trying to print out or cast to a string the resulting array. I thin=
k the problem may be happening due to the following chunk of code:
{
     PyObject* temp =3D PyArray_SimpleNewFromData(1, &numobjs, typeNum, dbV=
alues);     PyObject* temp2 =3D PyArray_FromArray((PyArrayObject*)temp, ((P=
yArrayObject*)temp)->descr, DEFAULT_FLAGS | ENSURECOPY);     Py_DECREF(temp=
);     PyDict_SetItemString(returnVal, "data", temp2);     Py_DECREF(temp2)=
;
}
=20
Lets assume that all my other inputs up this point are fine and that numobj=
s, typeNum, and dbValues are fine. Is their anything obviously wrong with t=
he above chunk of code? or does it appear ok? Ultimately the dictionary "re=
turnVal" is returned by the function this code came from, and everything el=
se is discarded. Any help is very greatly appreciated. Thanks in advance,
