(1)gethostname()、sethostname()函数,获取/设置本地主机的标准主机名
int main (int argc, char *argv[])
{
char buf[50];
if (gethostname(buf, sizeof(buf)) == 0)
{
printf("%s\n", buf);
}
else
{
perror("gethostname");
}
return 0;
}
程序输出:
[[email protected] ~]# ./a.out
localhost.localdomain
[[email protected] ~]#
int main (int argc, char *argv[])
{
char buf[50] = "localhost.localdomain";
if (sethostname(buf, strlen("localhost.localdomain")) < 0)
{
perror("sethostname");
}
else
{
printf("sethostname success!\n");
}
return 0;
}
程序输出:
[[email protected] ~]# ./a.out
sethostname success!
[[email protected] ~]#
(2)getdomainname()、setdomainname()函数,获取/设置本地主机的域名
int main (int argc, char *argv[])
{
char buf[50];
if (getdomainname(buf, sizeof(buf)) == 0)
{
printf("%s\n", buf);
}
else
{
perror("getdomainname");
}
return 0;
}
程序输出:
[[email protected] ~]# ./a.out
www.robot.com
[[email protected] ~]#
int main (int argc, char *argv[])
{
char buf[50] = "www.robot.com";
if (setdomainname(buf, sizeof("www.robot.com")) < 0)
{
perror("setdomainname");
}
else
{
printf("setdomainname success!\n");
}
return 0;
}
程序输出:
[[email protected] ~]# ./a.out
setdomainname success!
[[email protected] ~]#
