.Dt DOHOOKS 9
.Os
.Sh NAME
.Nm dohooks
.Nd run all hooks in a list
.Sh SYNOPSIS
.Fd #include <sys/systm.h>
.Ft void
.Fn dohooks "struct hook_desc_head *head"
.Sh DESCRIPTION
The
.Fn dohooks
function invokes all hooks established using the
.Xr hook_establish 9
function.
Hooks are called in the order of the TAILQ that
.Fa head
points to, however
.Xr hook_establish 9
can put the hooks either at the head or the tail of that queue,
making it possible to call the hooks either in the order of
establishment, or its reverse.
.Pp
This function is used to implement the
.Xr doshutdownhooks 9
as well as the
.Xr dostartuphooks 9
macros.
