Module Name:
winsmib.c
Abstract:
Sample SNMP Extension Agent for Windows NT.
These files (testdll.c, winsmib.c, and winsmib.h) provide an example of
how to structure an Extension Agent DLL which works in conjunction with
the SNMP Extendible Agent for Windows NT.
Extensive comments have been included to describe its structure and
operation. See also "Microsoft Windows/NT SNMP Programmer's Reference".
Created:
7-Oct-1991
