Thanks, Mike (and all!)--win32pdh led me to the answer.
My purpose was to determine when a NetMeeting session had ended. The problem
with NetMeeting is that program control returns after just a few seconds even if
NetMeeting is still running. So, recognizing that Microsoft typically provides
more than one way to skin its cats, I decided to use NetMeeting's process name
to determine if it was running.
Based on Mike's tip, I hunted through win32pdh, which led me to win32pdhutil. I
adapted the routine below from win32pdhutil's "GetPerformanceAttributes" to get
a list of the names of all processes; if "conf" (the secret code for
"NetMeeting") appears in the list, NetMeeting is presumed to still be running.
def GetProcessNames(object="Process", counter="ID Process",
if bRefresh: # PDH docs say this is how you do a refresh.
win32pdh.EnumObjects(None, machine, 0, 1)
items, names = win32pdh.EnumObjectItems(None, None, object, -1)
