There is a thinko that shows up in a couple of places:

http://starship.python.net/crew/mwh/toext/node5.html :

"PyArg_UnpackTuple returns 0 on success and -1 on failure." (and the following
discussion).

then http://starship.python.net/crew/mwh/toext/node7.html :

 "Attempting to pass values that cannot be implicitly converted to Python
integers - strings or files, say - will result in PyArg_ParseTuple setting an
exception or returning -1".

Of course, all the PyArg_XXX functions return true on success and false on
failure, as shown in your example code.
