Unp里写的那么清楚

自己先写点可以确认select工作原理的小段代码

多试试

int main(void) //Just for DHCP'mode
{
        printf("\n 000000000000000000 \n");

        FILE * stream = NULL;
        FILE * pFile = NULL;
        char buf[1024];
        memset(buf, 0, sizeof(buf));

        int i=0;
        int ret = 0;
        int fno = -1;
        int fn1 = -1;
        fd_set rfds;
        int maxFd;
        struct timeval timeout;

        if( (stream = popen("ping -c 3 192.168.0.1","r")) == NULL)
        {
                printf("popen error!\n");
                pclose(stream);
        }
        fno = fileno(stream);

啥子哟
