WinCe Wifi配置

大家好，关于wifi的配置, 下面黑体部分： g_dwOutput & INTF_BSSID == 0？？？？为什么啊？望高人指教！

部分打印信息：
In flags used    = [0x7fffffff]
dwOutput 打印信息 =  [0x000fffff]

代码如下：
BOOL GetFirstWirelessCard(  )
{
g_WirelessCard1[0] = L'\0';
/*
if( NULL == pCard ){
RETAILMSG(_DEBUG_WIFI_, (TEXT(" pCard == NULL, return ! \r\n ")));
return FALSE;
}
*/
INTFS_KEY_TABLE IntfsTable;
IntfsTable.dwNumIntfs = 0;
IntfsTable.pIntfs = NULL;

// 枚举系统中可用的无线网卡
DWORD dwStatus = WZCEnumInterfaces(NULL, &IntfsTable);

RETAILMSG(_DEBUG_WIFI_, (TEXT(" wifi.cpp, GetFirstWirelessCard(), dwStatus = %d \r\n "), dwStatus));

if (dwStatus != ERROR_SUCCESS)
{
      RETAILMSG(_DEBUG_WIFI_, (TEXT("WZCEnumInterfaces() error 0x%08X\n"),dwStatus));
      return FALSE;
}

// 判断无线网卡的数量，可以根据无线网卡数量来枚举出所有可用的无线网卡
RETAILMSG(_DEBUG_WIFI_, (TEXT(" wifi.cpp, GetFirstWirelessCard(), IntfsTable.dwNumIntfs = %d \r\n "), IntfsTable.dwNumIntfs));
if (!IntfsTable.dwNumIntfs)
{
      RETAILMSG(_DEBUG_WIFI_, (TEXT("System has no wireless card.\n")));
      return FALSE;
}
wcsncpy(g_WirelessCard1, IntfsTable.pIntfs[0].wszGuid, MAX_PATH-1);
// _tcscpy(pCard, IntfsTable.pIntfs[0].wszGuid);
wprintf(L"wireless card found: %s\n", g_WirelessCard1);
LocalFree(IntfsTable.pIntfs);

return TRUE;
}

void
PrintMacAddress
// some RAW_DATA is a MAC ADDRESS, this function is for printing MAC ADDRESS
(
IN PRAW_DATA prdMAC
)
{
if (prdMAC == NULL || prdMAC->dwDataLen == 0)
      _tprintf(L"");
else if(prdMAC->dwDataLen != 6)
      _tprintf(L"");
else
{
      _tprintf(L"%02X:%02X:%02X:%02X:%02X:%02X",
         prdMAC->pData[0],
         prdMAC->pData[1],
         prdMAC->pData[2],
         prdMAC->pData[3],
         prdMAC->pData[4],
         prdMAC->pData[5]);
}
} // PrintMacAddress()

BOOL GetWirelessCardInfo( )
{
//TCHAR *szWiFiCard = NULL;

// 初始化无线网卡信息
RETAILMSG(1, (TEXT(" wifi.cpp,  GetWirelessCardInfo() ...... \r\n")));
WCHAR *szWiFiCard = g_WirelessCard1;
memset(&g_Intf, 0, sizeof( INTF_ENTRY_EX ));
g_Intf.wszGuid = szWiFiCard;
g_dwOutput    = 0;
_tprintf(L" wifi.cpp,  g_Intf->wszGuid: = %s , g_WirelessCard1 = %s .....\r\n",
g_Intf.wszGuid,
g_WirelessCard1 );
// 查询无线网卡信息

DWORD dwStatus = WZCQueryInterfaceEx(
NULL,
INTF_ALL,
&g_Intf,
&g_dwOutput );

if (dwStatus != ERROR_SUCCESS)
{
      RETAILMSG(_DEBUG_WIFI_, (TEXT("WZCQueryInterfaceEx, GetWirelessCardInfo(), GetLastError( %d ) \n"), GetLastError()));
      return FALSE;
