REBOOT(2) Minix Programmer's Manual 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.
