INITIALIZATION
       The  init_snmp() function initialises the snmp_alarm subsystem by call-
       ing init_snmp_alarm() and then init_alarm_post_config() to set  up  the
       first  timer  to initialise the callback function.  These two functions
       should not be used directly by applications.

I think some how internally it would register init_myTable(); which init 
myTable mib code.

The sub agent file myTable_subagent.c calls this function (init_snmp()). I 
just wanna hold the values in table till the new values is ready to be 
updated [which basically takes time]. client process snmpwalk can travel it. 
without getting errors or timeout.
I tried NETSNMP_CACHE_AUTO_RELOAD, this also gives errors some time, i also 
tried in combination with other too, still not helpting.

Thanks
