WinSNMP Manager API

[This is preliminary documentation and subject to change.]

The Windows® SNMP Manager Application Programming Interface (the WinSNMP Manager API), version 1.1a, allows you to develop SNMP-based network management applications that execute in the Windows NT® operating environment, version 4.0 and later. The Simple Network Management Protocol (SNMP) is a request-response protocol that transfers management information between protocol entities.

WinSNMP has been jointly developed with the cooperation, input, and support from several companies, associations and individuals.

The first part of this overview provides information about SNMP versions, and a list of the relevant Requests for Comments (RFCs). It also describes the WinSNMP model, and the components and features of the Microsoft WinSNMP implementation. It also provides information about data management and communications concepts you need to program in the WinSNMP environment.

The second section discusses the WinSNMP functions and the following related WinSNMP programming tasks:

• Opening and closing a WinSNMP manager application
• Opening and closing a WinSNMP session
• Managing traps and notifications
• Working with variable binding lists
• Working with protocol data units
• Sending SNMP messages
• Receiving SNMP messages
• Managing object identifiers
• Freeing WinSNMP descriptors
• Setting the entity and context translation mode
• Managing the retransmission policy

You should be familiar with the basic concepts of SNMP and Windows programming before reading this overview. For additional information about SNMP, see Simple Network Management Protocol and the relevant Requests for Comments (RFCs) which are published by the Internet Engineering Task Force (IETF).
