dhcpmib.h

|
|
Abstract:
|
|
|
|
Sample SNMP Extension Agent for Windows NT.
|
|
|
|
These files (dhcpmibm.c, dhcpmib.c, and dhcpmib.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".
