Folks,

I am writing an extension where I follow the guide on the web 
(http://docs.python.org/3.3/extending/newtypes.html#generic-attribute-management). 
I have an object declared,

struct Object
{
     PyObject_HEAD
};

and a member set through tp_getset mechanism,

PyGetSetDef ObjectGetSet[] =
{
     {"mem", (getter)MemGet, (setter)MemSet, "mem-doc-string", NULL},
     {NULL}  /* Sentinel */
};

My question is - how do I access the doc string "mem-doc-string" 
supplied in the PyGetSetDef structure? If I type

print(obj.mem.__doc__)

then the __doc__ string for the result of a call to MemGet(...) is 
printed, not the doc string supplied in the PyGetSetDef structure.

Many thanks for the advice,

Nick Gnedin
