How to use the forbiddenfruit.__init__.PyFile function in forbiddenfruit

class PyFile(ctypes.Structure):
    pass

PyObject_p = ctypes.py_object
Inquiry_p = ctypes.CFUNCTYPE(ctypes.c_int, PyObject_p)
# return type is void* to allow ctypes to convert python integers to
# plain PyObject*
UnaryFunc_p = ctypes.CFUNCTYPE(ctypes.py_object, PyObject_p)

TernaryFunc_p = ctypes.CFUNCTYPE(ctypes.py_object, PyObject_p, PyObject_p, PyObject_p)
LenFunc_p = ctypes.CFUNCTYPE(Py_ssize_t, PyObject_p)
SSizeArgFunc_p = ctypes.CFUNCTYPE(ctypes.py_object, PyObject_p, Py_ssize_t)
SSizeObjArgProc_p = ctypes.CFUNCTYPE(ctypes.c_int, PyObject_p, Py_ssize_t, PyObject_p)
ObjObjProc_p = ctypes.CFUNCTYPE(ctypes.c_int, PyObject_p, PyObject_p)

FILE_p = ctypes.POINTER(PyFile)
