Description:
|
|
This program demonstrates the usage of special registry APIs
|
|
for collecting performance data.
|
|
|
|
C files used in this app:
|
|
pviewer.c - this file
|
|
pviewdat.c - updates the dialog
|
|
perfdata.c - gets performance data structures
|
|
objdata.c - access performance data objects
|
|
instdata.c - access performance data instances
|
|
cntrdata.c - access performance data counters
