This is a follow-up question to a recent thread. Dave Abrahams provided the following code to extract a c++ object from a PyObject void f(PyObject* p) { handle<> ph(borrowed(p)); MyObj* op = extract<MyObj*>(object(ph)); } this works beautifully, but appenrently fails in the case where MyObj is a simple function. That is typedef void (fcntptr*)(); void f(PyObject* p) { handle<> ph(borrowed(p)); fcntptr op = extract<fcntptr>(object(ph)); } results in the following compilation error message. /usr/local/include/boost/type_traits/add_cv.hpp:34: `const volatile' qualifiers cannot be applied to `void ()()' As always, any help/insight is greatly appreciated. -Francois ---------------------------------------------------------------------------- Dr. Jean-Francois OSTIGUY voice: (630) 840-2231 Beam Physics Dept MS220 FAX: (630) 840-6039 Fermi National Accelerator Laboratory email: ostiguy@fnal.gov Batavia IL 60510-0500 WWW:www-ap.fnal.gov/~ostiguy
