弱问dev_get及dev_get_by_name的使用

之前我一直没有接触设备的代码，今天因为需要使用dev_get和dev_get_by_name几个函数进行网络设备的控制，但是从没有接触过，dev_get 和dev_get_by_name需要包含哪些文件、如何进行编译才能顺利通过，不会出现undefined reference to...这种错误？

#include <netinet/in.h>

#include <linux/netdevice.h>

#include <stdio.h>

int main(){

    int ret=dev_get("eth0");

    if(!ret){

        puts("Device doesn't exist");

    }

    struct net_device *my=dev_get_by_name("eth0");

    return 0;

}

gcc -Wall -o "net" "net.c" (在目录/home/tyh中)
