WATCHDOG(9) BSD Kernel Developer's Manual WATCHDOG(9)NAME
watchdog -- software and hardware watchdog facility
SYNOPSIS
#include <sys/watchdog.h>
void
watchdog_fn(void *private, u_int cmd, int *error);
EVENTHANDLER_REGISTER(watchdog_list, watchdog_fn, private, 0);
EVENTHANDLER_DEREGISTER(watchdog_list, eventhandler_tag);
DESCRIPTION
To implement a watchdog in software or hardware, only a single function needs to be written and registered on the global watchdog_list.
The function must examine the cmd argument and act on it as follows:
If cmd is zero, the watchdog must be disabled and the error argument left untouched. If the watchdog cannot be disabled, the error argument
must be set to EOPNOTSUPP.
Else the watchdog should be reset and configured to a timeout of (1 << (cmd & WD_INTERVAL)) nanoseconds or larger and the error argument be
set to zero to signal arming of a watchdog.
If the watchdog cannot be configured to the proposed timeout, it must be disabled and the error argument left as is (to avoid hiding the arm-
ing of another watchdog).
There is no specification of what the watchdog should do when it times out, but a hardware reset or similar ``drastic but certain'' behaviour
is recommended.

Hi,
I am willing to build a script that does a "ps-ef" or "top" on a specific process, and if it finds it running to start another process.
Any suggestions to do this in a optimized way?
Thanks! (2 Replies)
