Module Name:
dhcpcext.h
Abstract:
defines, typedefs, prototypes to enable clients to interface with
dhcp client
Author:
Pradeepb 12/3/95
Revision History:
Notes:
Currently used by SHIVA for their RAS client. Currently, contains
stuff relevant only to poking DHCP client so that it notifies nbt (on WFW).
