Okay, I've figured it out:

---
int main(int argc, char **argv)
{
  PyObject *module, *dict, *foo, *result;
  char *path, *newpath;
  double x=5.5, y=6.6;

  Py_SetProgramName(argv[0]);
  Py_Initialize();
  path=Py_GetPath();
  newpath=strcat(path, ":.");
  PySys_SetPath(newpath);
  free(newpath);

  module=PyImport_ImportModule("exmpl");
  dict=PyModule_GetDict(module);
  foo=PyDict_GetItemString(dict, "foo");
  result=PyObject_CallFunction(foo, "dd", x, y);
  printf("The answer is %.2f!\n", PyFloat_AsDouble(result));

  Py_Finalize();

  return 0;
};
