在linux下如何通过代码获取wifi型号rt3370的连接状态及信号强度

[小黄老菜鸟]

下面是获取链接状态的代码，请问但一直没变，麻烦各位帮我分析一下原因！
char data[256]={0};
char name[10] = {0};
sprintf(name, "ra0");
strcpy(lwreq.ifr_name, name);
memset(data, 0, sizeof(rt_802_11_link_status));
lwreq.u.data.length = sizeof(rt_802_11_link_status);
lwreq.u.data.flags = RT_OID_802_11_QUERY_LINK_STATUS;
lwreq.u.data.pointer = data;
int iRet = ioctl(skfd, RT_PRIV_IOCTL, &lwreq);

参考iwlist scan源码

这个最好是厂家给驱动..
