Sorry, I will amend it!
But if i use NOTIFICATION-TYPE, can I send message as a SNMPv1 trap?
I don't realize the relationship between SMIv2 and SNMPv2

[MIB]
myMibTrap ::= { enterprise 920 }

demoTrap       NOTIFICATION-TYPE
STATUS         current
DESCRIPTION     "Send a message to the manager when the DHCP setting is
                             chaged"
::= { myMibTrap 1 }
[/MIB]

int specific = 1;
oid  trapOid = { SNMP_OID_ENTERPRISES, 920 };
oid flagOid = { PRIVATE_OID_DHCP_FLAG };
struct variable_list varList;

int testTrap_callback(int value) {

printf("Send a trap!!!!");
varList.next_variable = NULL;
varList.name = flagOid;
varList.name_length = sizeof(flagOid);
varList.type = ASN_INTEGER;
varList.val = value;
varList.val_len = sizeof(value);

send_enterprise_trap_vars( SNMP_TRAP_ENTERPRISESPECIFIC,
specific, trapOid, sizeof(trapOid), varList);

}

Is the above code right ? and does some useful function to set the
variable_list ^^
