[Boost-users] newbie: need example (call python from c++)

Hello,

I use call<void>(pyFunc,arg1,..) to call a python
function with standard double, int etc.

What must I do to call a function with a c++ object as
argument?

psydocode:

class MyAnimal
{
       /*...*/
       std::string __strName;
    public:
       MyAnimal() : __strName("Tux") {}
       /*...*/
       std::string getName()
           { return __strName;}
       void setName(const std::string &strName)
           { __strName = strName; }
};

int main()
{
  /*...*/
  MyAnimal* pTux = new Animal;
  /*do something with pTux*/

  /*use a python function with pTux*/
  call<void>(pyFunc1, ?pTux? );
  
  /*change attributes pTux in pyFunc2*/
  dog = call<MyAnimal>(pyFunc2, ?pTux?);

  /*if it possible to call by reference?*/
  call<void>(pyFunc3, ?pTux?);
  pTux->getName();// return Cat

}

python module:

def py_func1(a):
     print a.getName()

def py_func2(a):
     a.setName('Dog')
     return a

def py_funnc3(a):
     a.setName('Cat')
