function return -> input parameter

I am not certain if I cam extend recursive C function call using Python.
Image I want to construct a link list of alphabet implemented in C:
Alphabet A, B, C, D;
setNext( A, B );
It would be the same as saying:
setNext( A, getPrev(C) );
"getPrev(C)" returns B, the right type and answer for A. I could also
setNext( A, getPrev(getPrev(D)) );
"getPrev(D)" retuns C, recursively returns B.
I am getting confused when I am trying to extend the above:
1) Can I distinguish the calls and how? One should be using
"PyArg_Parse()", and the other using "PyEval_CallObject()".
2) The 2nd argument of function "PyEval_CallObject()" is expecting a
Python argument object. What if it is a recursive call? How can I
construct this argument which is a function call itself?
Thanks in advance.
