snmpCreateVarBinds parameters

varbinds: This output parameter is a pointer to the address of the SnmpVarBinds structure that is created and returned. This parameter is required.
numVarbinds: This input parameter specifies the number of variable bindings that will be part of the created SnmpVarBinds structure. This value must be greater than or equal to 0. If this value is 0, the oid and value parameters are ignored.
oid: This input parameter specifies the OID value for the first VarBind structure. If this parameter set to NULL, no VarBind structure is created within the SnmpVarBinds structure.
value: This input parameter is the address of the smiValue value of the VarBind structure that is to be created. This parameter is valid only if the oid parameter is specified. If an oid value is specified and the smiValue address is NULL, the created VarBind structure will contain an empty smiValue.
