The SnmpGetVb function retrieves variable binding information from a variable binding list. The function retrieves the variable name and the variable's associated value from the variable binding entry specified by the WinSNMP manager application.
To update variable binding entries in a variable binding list, call the SnmpSetVb function. The SnmpSetVb function also appends new variable binding entries to an existing variable binding list.
The WinSNMP manager application must call the SnmpDeleteVb function to remove entries from a variable binding list.
To retrieve, modify or delete a variable binding entry, the WinSNMP manager application must specify the position of the entry in the variable binding list.
A call to the SnmpSetPduData function associates a variable binding list with a PDU. A call to the SnmpGetPduData function retrieves a variable binding list from a PDU. An individual variable binding is not directly associated with a PDU, but it is indirectly associated through its inclusion in a variable binding list.
