- SMIVALUE CLASS DEFINITION
- DESIGN + AUTHOR: Jeff Meyer
- LANGUAGE:
- ANSI C++
- OPERATING SYSTEMS:
- MS-Windows Win32
- BSD UNIX
- DESCRIPTION:
- SMIValue class definition. Superclass for the various types
- of SNMP values (Address, Oid, Octet, etc.). Provides
- only a few functions, most info is in subclass.
