[C++-sig] POPEN Query

[Munshi, Shahid K. (Manpower Contract)]

I am trying to capture network traffic for 60 seconds using windump utility for windows under Windows 2000 Server platform.
When I open the Captured file , There is nothing in file....  Anybody explain me why ?

import os,win32pipe
TooMuchTime = 60
x = win32pipe.popen("windump > Test.txt",'w+')
w = time.time()
TotalTime = time.time() + TooMuchTime
while time.time() < TotalTime:
        time.sleep(1.0)
        print ".",
x.close()
