[capi-sig] DECREF when using PyDict_SetItem...

I'm using PyDict_SetItemString to add a long from a C struct into a Python dictionary. The full code is in the usn2dict function in here:

http://svn.timgolden.me.uk/extensions/change-journal/_usn.c

but the sort of thing I'm talking about is this:

PyDict_SetItemString ( dict, "RecordLength", PyLong_FromLongLong (usn_record->RecordLength) );

My understanding is that PyLong_FromLongLong passes its reference to my function, which then passes it to PyDict_Set... which INCREFs it. That means, I think, that my function should DECREF it before exit since I'm only creating it to store it in the dict. Is that correct?

In other words, should my code really do this?

record_length = PyLong_FromLongLong (usn_record->RecordLength); PyDict_SetItemString (dict, "RecordLength", record_length); Py_DECREF (record_length)

Thanks
