Build a PyObject* from a C function?

Question

I am embedding Python in a C++ library which I am making. I would like users to be able to pass C functions in the form of function pointers PyObject* (fpFunc*)(PyObje

Answer 1

Found it. Though it's not in the docs and it's hardly explicit in the source.

PyObject* (*fpFunc)(PyObject*,PyObject*) = someFunction;
PyMethodDef methd = {"methd",fpFunc,METH_VARARGS,"A new function"};
PyObject* name = PyString_FromString(methd.ml_name);
PyObject* pyfoo = PyCFunction_NewEx(&methd,NULL,name);
Py_DECREF(name);

It works. I can call the function like I normally would call a Python function object.

If you're curious, all I found in the doc was about Py_InitModule4 and loading modules, so I went to check Python's source, and found out about PyCFunction, then I looked around in the doc but I couldn't find anything about PyCFunction_NewEx, so I had to check the source to make sure it was as I thought.
