Why snmpdemo always stop after invoked by Master agent?

(1) I have useed "mibcodegen" to generate a code sample from "mib_demo.txt" which is in SUNWconn/sea/snmp/sample ;

(2) I have never modify any code except "Makefile"

(3) I use make to build a "snmpdemod" and reset snmpdemo.reg , snmpdemo.acl, snmpdemo.rsrc and snmpdemo.snmprelay;

(4) Then I run command as follow:

# ./snmpdx -y -c /etc/snmp/conf

# ps -ef | grep snmp

root 44011 0 09:10:08 pts/30:00 snmpdemod -p 8041 -i 4

root 43991 0 09:10:03 pts/30:00 ./snmpdx -y -c /etc/snmp/conf

(5) But after a moment ,snmpdemod had stopped .

Question:

(1) To be a daemon snmp subagent ,do I have to modify "agent_loop" in snmpdemo_appl.c ?

(2) Who could give me a code sample about "daemon"

I come from China , so I could not get more information about solaris,please help me .

Thanks in advance.
