REBOOT(3)						     Library Functions Manual							 REBOOT(3)

NAME

       reboot - reboot CPU after loss of file server connection

SYNOPSIS

       write(cfd, "push reboot", 11);

       fd = open("#^/deltat", OWRITE);
       fprint(fd, "%d", delaytime);

DESCRIPTION

       This  is a combined device and stream module (see stream(3)).  The bootstrap program boot(8) pushes the module onto the file server connec-
       tion of a CPU server.  The system will then reboot automatically if the connection hangs up.  The reboot may be postponed by delaytime mil-
       liseconds by writing the decimal value of delaytime to Conventionally, this is done by /rc/bin/cpurc (see cpurc(8)).  This mechanism may be
       used to cause the machines at a particular site to come up in a fixed order, such as after a power failure.

NAME

     reboot, halt -- stopping and restarting the system

SYNOPSIS

     halt [-lnq]
     reboot [-lnq]

DESCRIPTION

     The halt and reboot utilities flush the file system cache to disk, send all running processes a SIGTERM (and subsequently a SIGKILL) and,
     respectively, halt or restart the system.	The action is logged, including entering a shutdown record into the wtmp(5) file.

     The options are as follows:

     -l      The halt or reboot is not logged to the system log.  This option is intended for applications such as shutdown(8), that call reboot
	     or halt and log this themselves.

     -n      The file system cache is not flushed.  This option should probably not be used.

     -q      The system is halted or restarted quickly and ungracefully, and only the flushing of the file system cache is performed (if the -n
	     option is not specified).	This option should probably not be used.

     Normally, the shutdown(8) utility is used when the system needs to be halted or restarted, giving users advance warning of their impending
     doom and cleanly terminating specific programs.
