DOSHUTDOWNHOOKS(9) BSD Kernel Developer's Manual DOSHUTDOWNHOOKS(9)NAME
doshutdownhooks -- run all shutdown hooks
SYNOPSIS
void
doshutdownhooks(void);
DESCRIPTION
The doshutdownhooks routine is deprecated. Use pmf_system_shutdown(9) instead.
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 cpu_reboot() 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).

CPU_REBOOT(9) BSD Kernel Developer's Manual CPU_REBOOT(9)NAME
cpu_reboot -- halt or reboot the system
SYNOPSIS
#include <sys/reboot.h>
void
cpu_reboot(int howto, char *bootstr);
DESCRIPTION
The cpu_reboot() function handles final system shutdown, and either halts or reboots the system. The exact action to be taken is determined
by the flags passed in howto and by whether or not the system has finished autoconfiguration.
If the system has finished autoconfiguration, cpu_reboot() does the following:
1. Sets the boothowto system variable (see boothowto(9)) from the howto argument.
2. If this is the first invocation of cpu_reboot() and the RB_NOSYNC flag is not set in howto, syncs and unmounts the system disks by
calling vfs_shutdown(9) and sets the time of day clock by calling resettodr(9).
3. Disables interrupts.
4. If rebooting after a crash (i.e., if RB_DUMP is set in howto, but RB_HALT is not), saves a system crash dump.
5. Runs any shutdown hooks by calling pmf_system_shutdown(9).
6. Prints a message indicating that the system is about to be halted or rebooted.
7. If RB_HALT is set in howto, halts the system. Otherwise, reboots the system.
If the system has not finished autoconfiguration, cpu_reboot() runs any shutdown hooks by calling pmf_system_shutdown(9), prints a message,
and halts the system.
If RB_STRING is set in howto, then the parameter bootstr is passed to the system boot loader on some ports.

I have seen some misinformation regarding Unix file permissions. I will try to set the record straight. Take a look at this example of some output from ls:

sort -nr --key=1 ....
The output I get is:

Suppose I have a main() function with only one malloc statement allocating say some 1 gb memory. Also say my system has 1 gb of ram.
main()
{
malloc(1gb)
return(0)
}
The program above exits without freeing the memory.
In this case will the 1 gb of heap memory be returned... (9 Replies)
I'm trying to install a PGX32 video card on my Sparc 10 Ultra running Solaris 10.

Hey All,
Quick question...
I'm writing a short script to check if a continuous port is running on a server.
I'm using "ps -ef | grep -v grep | grep processName" and I was wondering if it was better/more reliable to just check the
return code from the command or if its better to pipe to... (12 Replies)
I installed NetBSD 6.1.2 amd64 and can't find the apm utility. Is it not in the base system?
Is it necessary to recompile the default amd64 kernel to use apm?
Or is there a new method for power management and suspend/resume? (2 Replies)
Hi,
I am learning shell scripting for the first time. I use AT&T Korn Shell, Version AJM 93u+ 2012-08-01, compiled from source on NetBSD.
So far I have managed to set up what I think is a useful and pleasing shell prompt, which can be seen in the image attached to this post.

Hey gang, I have a list of times I need to sum up. This list can vary from a few to a few thousand entries.

Usually when I on the evening go to bed I take some interesting book with me. I read it for a while to get me down to sleep. Probably most people seek information from the Nett by googleing but I am so oldfashioned I prefer a real book ;)
