i have question:call,c-->python-->c.
1.the c pointer void* abc="123" by pycapsule in the c code.
......
void* lpContext = "abc";
PyObject * lpPyContext = PyCapsule_New(lpContext, "Context",NULL);
......
PyTuple_SetItem(pArgs, 1, lpPyContext);
PyObject* pyResult = PyObject_CallObject(pFunc, pArgs);
2.c call python:
in the python code:
import ctypes
pycapsule = ctypes.windll.LoadLibrary("C:\Users\zhaoya16975\Documents\Visual
Studio 2017\Projects\cpython\Release\pycapsule.dll")
def test( lpContext,lpRequest,lpAnswer):
print lpContext
pycapsule.hello()
pycapsule.GetContext(lpContext)
.........
the lpContest is "<capsule object "Context" at 0x02747e00>"
but,i can't lpContext in the pycapsule.GetContest:
the capsule is null poniter,the GetContext no execute!!
void* FUNCTION_CALL_MODE GetContext(PyObject *capsule) {
printf(" GetContext......\n");
//if (!PyCapsule_IsValid((PyObject *)capsule, "Context")) {
// printf(" the Capsule Context is no Valid\n");
// return NULL;
//}
//return PyCapsule_GetPointer((PyObject *)capsule, "Context");
return NULL;
}
FUNCTION_CALL_MODE is __stdcall i think no problem.because, if
GetContext(PyObject *capsule) -->GetContext() is ok. PyObject *capsule from
python to c unknown error occurred.
i hope c call python pass void* ,and python call c pass void* ,but the capsule
call no success?_______________________________________________
