+.Dt DOSHUTDOWNHOOKS 9
+.Os
+.Sh NAME
+.Nm doshutdownhooks
+.Nd run all shutdown hooks
+.Sh SYNOPSIS
+.Ft void
+.Fn doshutdownhooks "void"
+.Sh DESCRIPTION
+.Em The
+.Nm
+.Em routine is deprecated.
+.Em Use
+.Xr pmf_system_shutdown 9
+.Em instead.
+.Pp
+The
+.Fn doshutdownhooks
+function invokes all shutdown hooks established using the
+.Xr shutdownhook_establish 9
+function.
+Shutdown hooks are called in reverse order, i.e.,
+the shutdown hook established last will be called first.
+.Pp
+This function is called from
+.Fn cpu_reboot
+with interrupts turned off.
+It is called immediately before the system is halted or rebooted,
+after file systems have been unmounted, after the clock has been updated,
+and after a system dump has been done (if necessary).
+.Sh SEE ALSO
+.Xr cpu_reboot 9 ,
+.Xr shutdownhook_establish 9
