snmpBuildPDU parameters

pdu

This output parameter is a pointer to the variable where the address of the SnmpPDU structure that is created is stored. This parameter is required.

snmpSession

This input parameter is the address of the SNMP session for which the SNMP PDU needs to be built. This parameter is the output parameter of the snmpBuildSession() function and is required.

pduType

This input parameter specifies the type of the PDU. This parameter is required. The valid values are:

SNMP_PDU_NULL: If used, the RFC-defined default PDU type SNMP_PDU_GETNEXT is built and returned
SNMP_PDU_GET
SNMP_PDU_GETNEXT
SNMP_PDU_SET
SNMP_PDU_GETBULK

varbinds

This input parameter is a pointer to the array of VarBind structures built using the snmpCreateVarBinds() and snmpAddVarBind() functions. This parameter is required.

non_repeaters

This input parameter is the number of non-repeaters for an SNMP_PDU_GETBULK request. This parameter is required, but is ignored if the pduType value is not SNMP_PDU_GETBULK.

max_repetitions

This input parameter specifies the maximum number of repetitions for an SNMP_PDU_GETBULK request. This parameter is required, but is ignored if the pduType value is not SNMP_PDU_GETBULK

req_id

This input parameter is a pointer to the request ID to be stored in the SnmpPDU field. If the value of this parameter is greater than or equal to 0, then this value is used. Otherwise, a random request ID is generated and stored in the SnmpPDU field.
