[C++-sig] [boost.python] void ptr problem

Hello,
I'm trying to use boost.python to wrap a C function that takes a pointer on a void pointer as an argument. But I'm going wrong to use the example from the FAQ. Could anyone help me on this?
my code looks like this:
struct void_;
BOOST_PYTHON_OPAQUE_SPECIALIZED_TYPE_ID(void_);
int myfunc(char * mychar, void ** mypointer);
int myfunc_wrp(char * mychar, void_ ** mypointer){
return myfunc(mychar,(void ** ) mypointer);
}
...
BOOST_PYTHON_MODULE(mymodule){
def("myfunc", &myfunc_wrp);
}
later in python I do:
import mymodule
mystring = " "
mypointerobject = 0
mymodule.myfunc(mystring,mypointerobject)
and get:
Boost.Python.ArgumentError: Python argument types in mymodule.myfunc(str, int)
did not match C++ signature:
myfunc(char *, struct void_ * *)
Are there any advices to solve this problem?
thank you for your answers.
Kind regards,
Michael
