changed approach

hi!,
I have chosen a different approach to my previous problem. I have added a signal handler to my C code which traps the signals occuring in any instance of my application and writes to a central log file.. which I keep on grep-ing through a script for further action. but, I am just dont have any idea about how make things happen by my first approach. any ideas to gimme any insight about how to proceed in the problem would be anxiously awaited.

SNMPTRAPFMT(8)						      System Manager's Manual						    SNMPTRAPFMT(8)

NAME
snmptrapfmt - Receive and log SNMP trap messages from a trap handler. SYNOPSIS
snmptrapfmt [-d num] [-D] [-f cfgfile] DESCRIPTION
Snmptrapfmt receives SNMP trap data through a local pipe. The trap data is written to this pipe by a SNMP trap handler which is called by snmptrapd (configuration is done in /etc/snmp/snmptrapd.conf) during the installation if this package. Snmptrapfmt formats the received trap data according to the specifications in the configuration file /etc/snmp/snmptrapfmt.conf (see this file for the syntax). The output of the snmptrapfmt application may be written to a log file or forwarded to the syslog daemon. The option -d 1 should be specified to enable tracing. Trace information is then written to the file /var/tmp/snmptrapfmt.trc. If the option -f cfgfile is given, the output of the daemon is configured via the mentioned configuration file. If this option is not spec- ified, a default output format is used. If the option -D is given, the the program will daemonize into the background. The syntax of the configuration file is explained in /etc/snmp/snmptrapfmt.conf ! FILES
/etc/init.d/snmptrapfmt is the start/stop script. /etc/snmp/snmptrapfmt.conf is the configuration file. /var/run/snmptrapfmt.pid is the PID file. /etc/snmp/snmptrapd.conf is the configuration file of the snmptrapd daemon, which calls the trap handler snmptrapfmthdlr. /usr/sbin/snmptrapfmt is the executable of the application. /usr/sbin/snmptrapfmthdlr is the executable of the trap handler. /var/run/snmptrapfmt.p is the communication pipe between the trap handler snmptrapfmthdlr and the formatter snmptrapfmt. /var/tmp/snmptrapfmt.trc is the trace file if the option -d is specified. /var/log/snmptrapfmt.log is the log file as specified in the configuration file.
