26460-6 Deliver smarter SNMP applications faster, with SNMP++ SNMP++ is Hewlett-Packard's new API for simplifying SNMP applications development using C++ and object-oriented techniques. For network management applications developers, though, SNMP++ is more than an API: it's a breakthrough. In this book, you'll learn how SNMP++ will help you build network management applications that are more portable, powerful, extensible and reliable. And if that's not enough, you'll also discover how SNMP++ can help you get to market faster than ever before. Written by a Hewlett-Packard engineer who helped develop SNMP++, this is the first book to cover the entire SNMP product development lifecycle, from analysis through design and implementation. Step-by-step, you'll learn how to use SNMP++ to build powerful applications with a minimum of coding effort. The book includes practical definitions and examples of every C++ class in the new SNMP++ class library. It shows how SNMP++ classes work together, covers cross-platform issues, extensibility and reuse.Finally, it walks through the construction of a complete network management application for Windows NT and Windows 95 using Microsoft's Visual C++ and the SNMP++ class library.
All source code is provided on CD-ROM. If you're a network management software developer, SNMP++ represents an extraordinary opportunity for competitive advantage-and this book puts you on the inside track.
