System Event Log The PanelView Plus CE platform provides a System Event Log wherein
applications can record system Events that are viewable in the
Hardware Monitor Properties applet in Control Panel. An Event can be
any condition that may be of interest to the user. In the PanelView
Plus CE, the Event log is implemented as the file
\storage card\Event.Log and as such is supported by all the standard
file amenities. It is fixed in size by EVENT_LOG_MAX_RECORDS and
holds at least 32 of the most recently logged Events. The Event Log
object wraps the Event Log such that applications need not be
concerned about creating, opening or closing the file.
