最近剛學會用boost.python調用簡單的c的函數,但是需要處理的是C++的類,我可以麻煩點把C++類都轉化成C語言函數,但是函數參數有數組的怎么辦?好吧,想到個土辦法,就是DLL里設個全局數組,python的數組用個循環,將數組的值一個個賦值給DLL里的全局變量。

給你一個例子看看,你就知道怎么做了
C++的接口
typedef struct{ unsigned long DeviceType; int Handle; int NumberOfClients; int SerialNumber; int MaxAllowedClients;}NeoDevice;int _stdcall icsneoFindNeoDevices(unsigned long DeviceTypes, NeoDevice *pNeoDevices, int *pNumberOfDevices); |
Python調用的代碼:
class NeoDevice(Structure): _fields_ = [("DeviceType",c_ulong), ("Handle",c_int), ("NumberOfClients",c_int), ("SerialNumber",c_int), ("MaxAllowedClients",c_int)]class cNeoVICan(CCanBase): def __init__(self): neoVi = windll.icsneo40 self.icsneoFindNeoDevices = neoVi.icsneoFindNeoDevicesif __name__ == "__main__": canBus = cNeoVICan() print canBus.icsneoGetDLLVersion() iNumberOfDevices = (NeoDevice * 10)() num = c_int() iResult = canBus.icsneoFindNeoDevices(c_ulong(65535), cast(iNumberOfDevices, POINT(NeoDevice)), byref(num)) |
