reboot

NAME

       reboot - reboot or disable Cntrl-Alt-Del

SYNOPSIS

       #include <unistd.h>

       int reboot (int magic, int magic_too, int flag);

DESCRIPTION

       reboot reboots the system, or enables/disables CAD.

       If  magic == 0xfee1dead && magictoo == 672274793, then the
       action performed will be based on flag.

       If flag = 0x1234567, then a hard reset is performed.
       If flag = 0x89abcdef, then CAD is enabled.
       If flag = 0, then CAD is disabled and a signal is sent  to
       process ID 1.

       Note that reboot() does not sync()!

       Only the super-user may use this function.

RETURN VALUE

       On  success,  zero is returned.  On error, -1 is returned,
       and errno is set appropriately.

ERRORS
