[C++-sig] Check number of arguments of a function object ?

[Marcus Jannes]

Hi again,

if i have a callable function object (PyObject*), how can i check the number of arguments this object has?
PyArg_ParseTuple does not seem to accomplish this.

def f(x): <- 1 argument
def f(x,y): <- 2 arguments

I want to make sure only functions with one argument get processed.
