Restart Mac OS X ungracefully using a C++ call?
原标题:

How do I restart Mac OS X using C++ (not Objetive-C) without invoking any child processes? Don t care if it s ungraceful.

system("reboot"); //Is not acceptable as it relies on invoking a process
最佳回答

I can t think why you wouldn t want to create a new process, but if you really don t want to, then execve("reboot",0,0) will run reboot, replacing the current process. You ll need to include <unistd.h>.

I m assuming this is available on Mac OS; it should be on all POSIX platforms.

UPDATE

It appears that Mac OS has a reboot system call. reboot(RB_AUTOBOOT); might do what you want. Or it might trash your hard drive. Be very careful when trying to work against the operating system like this.
