PyArray_FromAny() steals a reference to PyArray_Descr* dtype
Hello all, the docs are unclear as to the reference counting on the inputs to the numpy C function PyArray_FromAny(). multiarraymodule.c in the PyArray_InnerProduct() code seems to imply that a reference to dtype is stolen in the PyArray_FromAny process. Meaning that I don't need/can't have a Py_DECREF(). Can anyone confirm this? Thanks much, Brian -- Brian A.

Yes, the PyArray_FromAny steals a reference to the dtype object. This is done so you can build one on the fly doing something like PyArray_DescrFromType(NPY_DOUBLE) inline with the PyArray_FromAny call. -Travis On Feb 15, 2012, at 4:23 PM, Larsen, Brian A wrote:
