Calling Python function with C pointer to struct as parameter

I am calling a Python function with a set of parameters, as an example.

VOID CallPythonFunction(
      PSOME_COMPLEX_STRUCT Parameter1
    , PSOME_COMPLEX_STRUCT Parameter2
    , PSOME_COMPLEX_STRUCT Parameter3
    , PSOME_COMPLEX_STRUCT Parameter4
    )
{
    PyObject* module_name = PyString_FromString((char*)"plugin");
    PyObject* plugin = PyImport_Import(module_name);
    PyObject* PyTargetFunction = PyObject_GetAttrString(plugin, (char*)"some_function");
    PyObject* args = PyTuple_Pack(4
        , PyLong_FromUnsignedLong((ULONG) Paramater1)
        , PyLong_FromUnsignedLong((ULONG) Paramater2)
        , PyLong_FromUnsignedLong((ULONG) Paramater3)
        , PyLong_FromUnsignedLong((ULONG) Paramater4)
        );
    PyObject* result = PyObject_CallObject(PyTargetFunction, args);
}

This parameters ain't standard C types but pointers to complex structs instead, for example.

typedef struct _SOME_COMPLEX_STRUCT 
{
    int field1;
    char field2;
    int  whatever;
} SOME_COMPLEX_STRUCT, *PSOME_COMPLEX_STRUCT;

Since I converted it to python int objects I am not sure of how to handle this with ctypes or if I should create a Python object instead.

def some_function(parameter1, parameter2, parameter3, parameter4):
    pass

There is any "better"/canonical way to pass this structs as parameters?

How can I modify the data from Python module? I am using ctypes.
