python - 拡張 Python、enum の処理方法

Question

拡張された Python の概念を使用してラッパー ルーチンを作成していますが、列挙型の処理方法がわかりません。基本的に、入力の1つを取るac関数はenumです。どの形式オプションを使用する必要がありますか?

typedef enum
{
    ISOUTPUT = 'W',
    ISINPUT = 'R'
} myenum;

int func1( i int, b myenum)

私のラッパールーチン:

static PyObject *Wrapper_func1(PyObject *self, PyObject *args)
{
    int x, result;
    myenum y;    
    PyArg_ParseTuple(args,"iC",x,y);
    result= func1(x, y);
    return Py_BuildValue("i",result);   
}

Pythonスクリプトで

import mymodule

x= mymodule.func1(1,'R') --- giving attribute error, when I debugged I found it is giving segment violation,
