gcc和llvm linux关闭函数来自c代码

Question

Linux x86-64与gcc编译和静态链接我有:

#include <sys/reboot.h>

if (str[0] == 'r')
  reboot(0x1234567);

但我似乎无法找到等效函数调用shutdown.如果不同,我也想知道llvm函数.

Answer 1

来自sys/reboot.h:

/* Perform a hard reset now.  */
#define RB_AUTOBOOT     0x01234567

[...]

/* Stop system and switch power off if possible.  */
#define RB_POWER_OFF    0x4321fedc

所以reboot(0x4321fedc);或reboot(RB_POWER_OFF);应该工作.
