Hello!
Thanks. That tip will help me to debug programs.
Also I would like to know result of subagent connection inside of code,
fail/success of init_snmp() function.
I have found a workaround, see below
if(snmp_callback_available(SNMP_CALLBACK_APPLICATION,SNMPD_CALLBACK_REGISTER_OID)
!= SNMPERR_SUCCESS)
{
cerr<<"NOT CONNECTED"<<endl;
}
else
{
cerr<<"CONNECTED"<<endl;
}
As I saw in net-snmp code in case of success connection some callbacks are
registered. So, one of way to check success connection is checking
for SNMPD_CALLBACK_REGISTER_OID. I do not think is a right way because this
call back can be set in other places of code of next net-snmp library
releases or it now can be set in other ones.
Thanks in advance.
