其实对于自己装了网卡驱动的来说,应该从最根本的驱动中获取速率。
但是用ioctl()也可以,其实实现和iwconfig命令相同。
仅仅获取速率这部分:
[cpp] view plain copy
- #include <stdio.h>
- #include <stdlib.h>
- #include <sys/socket.h>
- #include <string.h>
- #include "wireless_copy.h"
- #define dvname "ath0"
- int get_rate(int sock, struct iwreq* wrq,__s32 rate);
- int main()
- {
- struct iwreq wrq;
- int sock;
- char gInterfaceName[16];
- __s32 rate;
- memset(gInterfaceName, 0, sizeof(gInterfaceName));
- strcat(gInterfaceName,dvname);
- sock = socket(AF_INET, SOCK_DGRAM, 0);
- if (sock < 0)
- {
- printf("Error Creating Socket for ioctl/n");
- return 0;
- }
- memset(&wrq, 0, sizeof(wrq));
- strncpy(wrq.ifr_name, gInterfaceName, IFNAMSIZ);
- get_rate(sock, &wrq,rate);
- printf("/nrate:%dM/n/n",wrq.u.bitrate.value/1000000);
- return 0;
- }
- int get_rate(int sock, struct iwreq* wrq,__s32 rate)
- {
- if(ioctl(sock, SIOCGIWRATE, wrq) < 0)
- {
- perror("Ioctl error");
- return(0);
- }
- return 1;
- }
其中wireless_copy.h可以从madwifi /tools 文件夹中找到。
