snmpBuildV2TrapOrInformPDU – Builds an SNMP V2 trap or inform PDU

#include <snmpntfy.h>
int snmpBuildPDU(SnmpPDU **pdu, const SnmpSession *snmpSession , 
                 const int pduType, const SnmpVarBinds *varbinds, 
                 smiUINT32 *req_id)

Rules:

The snmpBuildSession() and snmpCreateVarBinds() functions must have been successfully called before calling this function, because the output from the snmpBuildSession() and snmpCreateVarBinds() functions is required as input for this function. After you are finished using the SnmpPDU structure created by this function, you must free the storage allocated by calling the snmpFreePDU() function.
SNMPv2 traps and informs require the following two VarBind structures in the VarBind array:
- sysUpTime
- snmpTrapOid
Your SNMP manager must call the snmpCreateVarBinds() and snmpAddVarBind() functions to create these VarBind structures, in this order, before calling this function
