NAME
dostartuphooks —
run all startup hooks
SYNOPSIS
#include
<sys/types.h>
#include <sys/systm.h>
void
dostartuphooks(void);
DESCRIPTION
The
dostartuphooks()
function invokes all startup hooks established using the
startuphook_establish(9) function. Startup hooks are called
in order, i.e., the startup hook established first will be called first.
This function is called from
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
iop(4) and
ioprbs(4) drivers, is a good example.
Startup hooks are, like shutdown hooks, implemented via the more general dohooks(9) API.
