NAME    [Toc]    [Back]

     doshutdownhooks - run all shutdown hooks

SYNOPSIS    [Toc]    [Back]

     #include <sys/types.h>
     #include <sys/systm.h>

     void
     doshutdownhooks(void);

DESCRIPTION    [Toc]    [Back]

     The doshutdownhooks() function invokes  all  shutdown  hooks
established using
  the shutdownhook_establish(9) function.  Shutdown hooks
are called in
     reverse order, i.e., the shutdown hook established last will
be called
     first.

     This  function is called from boot(9) 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).

     Shutdown hooks are, like startup hooks, implemented via  the
more general
     dohooks(9) API.
