求助：网络发送结构体的字节序问题

化了妆的幸福呀 2014-01-18 11:58:07

刚学网络编程不久，在做一个接受功能的时候，发现字节序不正确。
发送端主要部分：

#pragma pack(1)

	struct Msg1{

		BYTE num;

		BYTE iden;

		short len;

		short avalia;

		int path;

		int pitch;

		int roll;

	}msg1;

	msg1.num=0x00;

	msg1.iden=0xb0;

	msg1.len=htons(0x0012);

	UpdateData();

	if (m_pose==0)

	{

		msg1.avalia=htons(0x0000);

		

	} 

	else

	{

		msg1.avalia=htons(0x0001);

	}

msg1.path=htonl(0x12345678);

msg1.pitch=htonl(0x09876543);

msg1.roll=htonl(0x01100220);



	char SendBuffer[18];





	memcpy(SendBuffer,&msg1,sizeof(msg1));

	sendto(m_socket,SendBuffer,18,0,

				(SOCKADDR*)&addrTo,sizeof(SOCKADDR));

接收端主要部分：

DWORD WINAPI CFistDlg::RecvProc(LPVOID lpParameter)

{

	SOCKET sock=((RECVPARAM*)lpParameter)->sock;

	HWND hwnd=((RECVPARAM*)lpParameter)->hwnd;

	

	SOCKADDR_IN addrRecv;

	int len = sizeof(SOCKADDR); 

	

	char recvBuf[100];



	

	int recvRst;

	CString recvStr;

	

	while(TRUE)

	{

			recvRst = recvfrom(sock, recvBuf, 100, 0, (SOCKADDR*)&addrRecv, &len);

		

		if (SOCKET_ERROR == recvRst)

		{

			

			break;

		}



		::PostMessage(hwnd, WM_RECVDATA, 0, (LPARAM)recvBuf);

		

	}

	return 0;

}







void CFistDlg::OnRecvData(WPARAM wParam,LPARAM lParam)

{

typedef struct AA

	{

	  BYTE num;

	  BYTE iden;

	  short len;

	  short avalia;

	  int path;

	  int pitch;

	  int roll;

	}aa;

AA *paa=(AA *)lParam;



SetDlgItemInt(IDC_EDIT_RECV,paa->num);

SetDlgItemInt(IDC_EDIT1,paa->iden);

SetDlgItemInt(IDC_EDIT2,ntohs(paa->len));

SetDlgItemInt(IDC_EDIT3,ntohs(paa->avalia));

SetDlgItemInt(IDC_EDIT4,ntohl(paa->path));

SetDlgItemInt(IDC_EDIT5,ntohl(paa->pitch));

SetDlgItemInt(IDC_EDIT6,ntohl(paa->roll));

}
