创建套接字失败解决思路

BOOL CChDlg::InitSocket()
{
    m_socket = socket(AF_INET,SOCK_DGRAM,0);
    if (INVALID_SOCKET==m_socket)
    {
        AfxMessageBox("失败INIT");
        return FALSE;
    }
    SOCKADDR_IN addrSock;
    addrSock.sin_addr.S_un.S_addr = htonl(INADDR_ANY);
    addrSock.sin_family=AF_INET;
    addrSock.sin_port = htons(6000);

    int retval;
    
    retval = bind(m_socket,(SOCKADDR*)&addrSock,sizeof(SOCKADDR));
    if (SOCKET_ERROR==retval)
    {
        closesocket(m_socket);
        AfxMessageBox("绑定失败");
        return FALSE;
    }
    return TRUE;
}
