Bluetooth发送问题

[Yao_2002]

int CBTDemoDlg::SendData(char *pszData, int nSize,int *pnError)
{
	if(!m_bConnect)
		return 0;
	
	char szHeader[5];
	char szBuffer[1050];
	char *pszDataBegin = NULL;
	int nDataLen;
	int nTotalLen;

	memset(szHeader, 0, sizeof(szHeader));
	memset(szBuffer, 0, sizeof(szBuffer));
	
	nDataLen = strlen(pszData);
	_itoa(nDataLen,szHeader,10);
	
	nTotalLen = nDataLen + 5;
	strcpy(szBuffer,szHeader);

	strcat(szBuffer,pszData);
	pszDataBegin = szBuffer;

	for(int i = 0;i < nTotalLen/MAX_DATA_LEN; i++)
	{
		int nSend = m_btConnect.Send(pszDataBegin,nTotalLen); 
		if(nSend == SOCKET_ERROR)
		{
			*pnError = GetLastError();
			return 0;
		}
		pszDataBegin += MAX_DATA_LEN;
	}

	if(nTotalLen % MAX_DATA_LEN)
	{ 
		int nSend = m_btConnect.Send(pszDataBegin,nTotalLen%MAX_DATA_LEN);
		if(nSend == SOCKET_ERROR)
		{
			*pnError = GetLastError();
			return 0;
		}
	}

	return 1;
}

这样来发送文件会有问题吗?
