2018-08-18 14:45c# 调用c++ sdk 传结构体指针
5本人菜鸟一枚
SDK函数 LIBBVCU_API BVCU_Result BVCU_Initialize( const BVCU_GlobalParam* pParam);
其中 BVCU_GlobalParam为结构体
typedef struct _BVCU_GlobalParam
{
int iSize;
void (*OnEvent)(int iEventCode, void* pParam);
int iReserved[4];
}BVCU_GlobalParam;
问题我是该直接传递一个指针,还是传一个BVCU_GlobalParam类型参数
public IntPtr m_bvcuSdkHandle;
BVCU_Initialize(ref Im_bvcuSdkHandle)(指针)
还是 BVCU_Initialize(ref _BVCU_GlobalParam bg) (结构体)
[DllImport("libBVCU.dll", CallingConvention = CallingConvention.Cdecl)]
public static extern int BVCU_Initialize(ref IntPtr handle);
[StructLayout(LayoutKind.Sequential)]
public struct BVCU_GlobalParam
{
public int iSize;
public CallbackDelegate OnEvent;
[MarshalAs(UnmanagedType.ByValArray, SizeConst = 4)]
public int[] iReserved;
};
这两种都试了,接口返回还是参数不符合,请大神上码指教
