send_v2trap doesn't work for me.

Greetings everyone!

I am a newbie to the net-snmp world. I have written a MIB and used
mib2c to generate the corresponding c code (say fooMIB.h and fooMIB.c).
The fooMIB.c has declarations to send a trap in a function called
send_Foo_Trap() which calls send_v2trap as follows:
int send_Foo_trap( void )
{
netsnmp_variable_list *var_list = NULL;
oid ppSystemStartup_oid[] = { 1,3,6,1,4,1,8707,2,1,1,20 };

snmp_varlist_add_variable(&var_list,
snmptrap_oid, OID_LENGTH(snmptrap_oid),
ASN_OBJECT_ID,
(u_char*)ppSystemStartup_oid,
OID_LENGTH(ppSystemStartup_oid)*sizeof(oid));

send_v2trap( var_list );
snmp_free_varbind( var_list );
DEBUGMSGTL(("fooMIB","Sent Foo_trap\n"));
return SNMP_ERR_NOERROR;

}

Now my question is if I have to send the trap from my application code,
do I just need to call the send_Foo_trap from within the application?
When I do so, I do not see trap being sent out in snmpd.log (I start
snmpd with -DALL and I do not even see the fooMIB message (the
DEBUGMSGTL in send_Foo_trap())in the snmpd.log) however I do see the
fooMIB getting initialized in the snmpd.log.

I will appreciate any help offered in this regard.

Thanks,
Abhinav.
