ubuntu c++ 关机 重启 挂起 API

#include <unistd.h>
#include <linux/reboot.h>

int main() {
    reboot(LINUX_REBOOT_MAGIC1,
           LINUX_REBOOT_MAGIC2,
           LINUX_REBOOT_CMD_POWER_OFF, 0);
    //   sync();
    //    reboot(LINUX_REBOOT_CMD_POWER_OFF);
}
Of course, you will need sufficient privileges to use this syscall.
必须有root权限哦
