Module Name:

virtual.h
|
|
|
|
Abstract:
|
|
|
|
Public declarations for the Change Virtual Memory dialog of the System
|
|
Control Panel Applet
|
|
|
|
Notes:
|
|
|
|
The virtual memory settings and the crash dump (core dump) settings
|
|
are tightly-coupled. Therefore, virtual.c and virtual.h have some
|
|
heavy dependencies on crashdmp.c and startup.h (and vice versa).
