我试图从我的C#程序中的C ++ DLL文件中调用某些函数。但是当涉及到指针时,我陷入了困境。有人可以指出我正确的方向吗?
这是带有目标函数的C ++头文件:
#pragma once
#ifdef STCL_DEVICES_DLL
#define STCL_DEVICES_EXPORT extern "C" _declspec(dllexport)
#else
#define STCL_DEVICES_EXPORT extern "C" _declspec(dllimport)
#endif
enum SD_ERR
{
SD_ERR_OK = 0,
SD_ERR_FAIL,
SD_ERR_DLL_NOT_OPEN,
SD_ERR_INVALID_DEVICE, //device with such index doesn't exist
SD_ERR_FRAME_NOT_SENT,
};
#pragma pack (1)
struct LaserPoint
{
WORD x;
WORD y;
byte colors[6];
};
struct DeviceInfo
{
DWORD maxScanrate;
DWORD minScanrate;
DWORD maxNumOfPoints;
char type[32];
};
//////////////////////////////////////////////////////////////////////////
///Must be called when starting to use
//////////////////////////////////////////////////////////////////////////
STCL_DEVICES_EXPORT int OpenDll();
//////////////////////////////////////////////////////////////////////////
///Search for .NET devices (Moncha.NET now)
///Must be called after OpenDll, but before CreateDeviceList!
///In pNumOfFoundDevs can return number of found devices (optional)
//////////////////////////////////////////////////////////////////////////
STCL_DEVICES_EXPORT int SearchForNETDevices(DWORD* pNumOfFoundDevs);
//////////////////////////////////////////////////////////////////////////
///All devices will be closed and all resources deleted
//////////////////////////////////////////////////////////////////////////
STCL_DEVICES_EXPORT void CloseDll();
此外,如何处理其他函数参数,例如WCHAR **和structsDeviceInfo和LaserPoint?
