I'm trying to do some cleanup (write open files) when Linux shuts down. I thought the right method would be to trap SIGTERM and do the necessary processing. Here's my sample code:
Code:
#include <stdio.h> // for File I/O
#include <signal.h> // for signals
#include <unistd.h> // for sleep()
void handler(int signal)
{
FILE *out=fopen("test.txt","at");
if (out)
{
fprintf(out,"got %d\n",signal);
fclose(out);
}
}
int main()
{
signal(SIGTERM,handler);
signal(SIGINT,handler);
sleep(30);
}
When I run this, and press Ctrl-C, it writes "got 2" to test.txt. However, if I logout/reboot, nothing is written to the file.

dxshutdown
dxshutdown(8) System Manager's Manual dxshutdown(8)NAME
dxshutdown - Performs various types of automated system shutdown.
SYNOPSIS
/usr/bin/X11/dxshutdown
OPTIONS
The dxshutdown command accepts all of the standard X Toolkit command-line options, which are documented in the OPTIONS section of the X(1X)
reference page.
DESCRIPTION
The Shutdown Manager application, dxshutdown, provides the system administrator with a graphical user interface for running user-specified
scripts at shutdown time in addition to performing the following types of automated system shutdown: Halt (and restart console mode) Reboot
Single-user mode shutdown Message-only shutdown
Dependencies: None. You do not need to configure anything prior to running Shutdown Manager.
You must be root to run Shutdown Manager.
Shutdown Manager also lets the system administrator display one or more warning messages prior to system shutdown. The dxshutdown command
uses the Tru64 UNIX shutdown command as an API, passing command-line arguments as specified by application defaults and user inputs.
The Shutdown Manager also provides the following features, which the shutdown command does not provide: Selection of a preshutdown script
to be executed prior to system shutdown Easy cancellation for a shutdown while the timed countdown is in progress Maintenance of an error-
and-script output log under /var/adm/sysman/dxshutdown.log Saving and restoring user-selected shutdown options over multiple invocations of
the Shutdown Manager application
For additional information about the graphical user interface, see the online help volume, which is available from the Help button in the
main window of the Shutdown Manager application.
To start dxshutdown from the graphical user interface: Click on the Application Manager icon on the CDE front panel. Double click on the
System_Admin application group icon. Double click on the Daily Admin application group icon. Double click on the Shutdown Manager appli-
cation icon.
EXAMPLES

the following command: /usr/dt/bin/dthelpview -h /usr/dt/appconfig/help/C/DXshutdown.sdl
