In a control message, the varbinds identify the nodes or instances to be added or removed from the master agents MIB tree. In a query message, the varbinds identify the variables to be gotten or set. In a trap message sent from a subagent to its master agent, the varbinds specify the objects to be sent in a trap message to the SNMP manager. A trap message from a subagent follows the SNMPv2 trap style. Thus, the first object in the list must always be <b>sysUpTime</b>. The second object must be a <b>snmpTrapOID.0</b> whose value is the administratively assigned name of the notification.</div><br><dd><div class="Indent"><a name="89470"> </a><i class="i">pHdr <br></i>Expects a pointer to a <b>SA_HEADER_T</b> structure containing all the items that go into the message header.</div><br><dd><div class="Indent"><a name="89471"> </a><i class="i">pDemuxer <br></i>Expects a pointer to an <b>SA_DEMUX_T</b> structure containing all the information the subagent might need to demux the packet.

In a v2 request, the string is the local entity string from the context and the Object ID is the local time ID from the context.</div><br><dd><div class="Indent"><a name="89472"> </a><i class="i">pBuf <br></i>Expects a pointer to an EBUFFER_T structure into which <b class="routine"><i class="routine">snmpSubEncode</i></b><b>( )</b> can write the encoded packet.
