Passing python objects as arguments to C/C++ function using ctypes

Question

I have a dll with a function that takes PyObject as argument something like

void MyFunction(PyObject* obj)
{
    PyObject *func, *res, *test;

    //function         


        

Answer 1

I made the following changes to your code and it worked for me, but I'm not sure it is 100% correct way to do it:

1. Use PYFUNCTYPE.
2. Just pass the python class object.

For example:

prototype = c.PYFUNCTYPE(    
    c.c_char_p,                
    c.py_object
)

func = prototype(('MyFunction', libTest))

func( MyClass )
