.Dt DOSTARTUPHOOKS 9
.Os
.Sh NAME
.Nm dostartuphooks
.Nd run all startup hooks
.Sh SYNOPSIS
.Ft void
.Fn dostartuphooks "void"
.Sh DESCRIPTION
The
.Fn dostartuphooks
function invokes all startup hooks established using the
.Xr startuphook_establish 9
function.
Startup hooks are called in order, i.e.,
the startup hook established first will be called first.
.Pp
This function is called from
.Fn main
with interrupts turned on.
It is called immediately before the system configures its root and swap
devices, but fully after all normal autoconfiguration.
This can be used to let device subsystems needing delayed configuration (e.g.,
due to very long initialization times) still provide the root device.
The
I2O system, implemented by the
.Xr iop 4
and
.Xr ioprbs 4
drivers, is a good example.
.Pp
Startup hooks are, like shutdown hooks, implemented via the more general
.Xr dohooks 9
API.
