Embedding Python and adding C functions to the interpreter

Question

I'm currently writing an applications that embedds the python interpreter. The idea is to have the program call user specified scripts on certain events in the program. I managed this part but now I want the scripts to be able to call functions in my program.

Here's my code so far:

#include "python.h"


static PyObject* myTest(PyObject* self,PyObject *args)
{
    return Py_BuildValue("s","123456789");
}

static PyMethodDef myMethods[] = {{"myTest",myTest},{NULL,NULL}};

int main()
{

    Py_Initialize();
    Py_InitModule("PROGRAM",myMethods);

    PyRun_SimpleString("print PROGRAM.myTest()");


    Py_Finalize();
}

Thanks!

You need to bind that function to some module, see http://docs.python.org/extending/embedding.html#extending-embedded-python

Edit: Basicly your code should work. Whats not working?

Haha, a single PyRun_SimpleString("import PROGRAM"); was all that needed to get it to work!
