STAILQ_NEXT after the wifi_softap_get_station_info() always return NULL ?

2017-08-11T11:54:18+08:00

HI
I let the ESP8266 to be the softAP, use one mobilephone to connect it , then use another mobilephone to connect it. So currently there are 2 client connected.
How can I　get the IP of two clients?

my code is:

Code:

number_client= wifi_softap_get_station_num();
       stat_info = wifi_softap_get_station_info();
       while(stat_info==NULL)
       {
          vTaskDelay(100/ portTICK_RATE_MS);
          stat_info = wifi_softap_get_station_info();
       }

       for(i=0;i       {
          os_printf("the client info is :[bssid : "MACSTR", ip : "IPSTR"]\n", MAC2STR(stat_info->bssid), IP2STR(&stat_info->ip));
          if(i<(number_client-1))
          {
             stat_info_bakup=stat_info;
             stat_info = STAILQ_NEXT(stat_info_bakup, next);
             while(stat_info==NULL)
            {
               vTaskDelay(200/ portTICK_RATE_MS);
               stat_info = STAILQ_NEXT(stat_info_bakup, next);
            }
          }
       }
        wifi_softap_free_station_info();[/color][/color]

I can get the number_client is 2, and it can printf the first client IP information.
But after
stat_info = STAILQ_NEXT(stat_info_bakup, next);

the stat_info is always NULL.
I have no idea about the STAILQ_NEXT.
Could somebody help me?
