Updating a PDU

  • Article

A WinSNMP application can retrieve and update selected PDU fields by using the SnmpGetPduData and the SnmpSetPduData functions.

The application can retrieve the PDU type, request identifier, error status, and error index fields from a specific PDU. It can also retrieve the handle to the variable binding list. The application can update the PDU_type and request_id fields.

If the PDU type is equal to SNMP_PDU_GETBULK, the application can also update the non_repeaters and the max_repetitions fields of the PDU.
