NAME
boot - halt or reboot the systemSYNOPSIS
In sys/types.h In sys/systm.h In sys/reboot.h Ft void Fn boot int howtoDESCRIPTION
The Fn boot function handles final system shutdown, and either halts or reboots the system. The exact action to be taken is determined by the flags passed in Fa howto and by whether or not the system has finished autoconfiguration.If the system has finished autoconfiguration, Fn boot does the following:
- If this is the first invocation of Fn boot and the RB_NOSYNC flag is not set in Fa howto , syncs and unmounts the system disks by calling vfs_unmountall9.
- Disables interrupts.
- If rebooting after a crash (i.e., if RB_DUMP is set in Fa howto , but RB_HALT is not), saves a system crash dump.
- Runs any shutdown hooks previously registered.
- Prints a message indicating that the system is about to be halted or rebooted.
- If RB_HALT is set in Fa howto , halts the system. Otherwise, reboots the system.
If the system has not finished autoconfiguration, Fn boot runs any shutdown hooks previously registered, prints a message, and halts the system.
