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
