- 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.
