As far as calling function goes, calling the _CFuncPtr effectively calls tp_call field which is PyCFuncPtr_call: highlight 複製 static PyObject * PyCFuncPtr_call(PyCFuncPtrObject *self, PyObject *inargs, PyObject *kwds) { // ... callargs = _build...
Since every process effectively has kernel32.dll loaded in the process, you’ll always load kernel32 successfully.Let’s say we built our dll as MyDll, and try to load it:highlight 复制 >>> cdll.MyDll Traceback (most recent call last): File "<stdin>", line 1, in <module>...

使用ctypes将Python函数转换成C function,传入C++中进行调用。 importctypes#set return and paramscfunc=ctypes.CFUNCTYPE(ctypes.c_int,# return typectypes.c_int,# arg0 typectypes.c_int# arg1 type)#Convert to C functionf=cfunc(add)# Call Python func in Cprint(_LIB.call_py_func(f,5,1)) ...
from ctypes import * # give location of dll dll1 = cdll.LoadLibrary('test.dll') dll2 = CDLL('test.dll') # the dll must be created under cl.exe, NOT in Visual Studio, which changes function name. result1= dll1.sum(1,3)
