REBOOT(2)

NAME
reboot - close down the system or reboot

SYNTAX
#define _MINIX_SOURCE 1
#include <unistd.h>
int reboot(int how, ...)

DESCRIPTION
Reboot() is used to close down the system. It allows several ways of shutting down depending on how:

reboot(RBT_HALT)
    Halt the system and return to the monitor prompt.

reboot(RBT_REBOOT)
    Reboot the system by letting the monitor execute the "boot" command.

reboot(RBT_PANIC)
    Cause a system panic. This is not normally done from user mode, but by servers using the sys_abort() kernel call.

reboot(RBT_MONITOR, code, length)
    Halt the system and let the monitor execute the given code of the given length. (code is of type char * and length of type size_t.)

reboot(RBT_RESET)
    Reboot the system with a hardware reset.

Reboot() may only be executed by the super-user.

DIAGNOSTICS
If the call succeeds, it never returns. If something went wrong, the return value is -1 and an error is indicated by errno.

SEE ALSO
shutdown(8), reboot(8), halt(8), sync(1).

NOTES
Minix can not return to the monitor if running in real mode, or if started from MS-DOS. This means that most of the reboot functions will change to a reset.
