can try to run up an example.

I Tried the PID method, and the Taskkill method, and neither worked.
This is what I get for trying to work on a windows machine. If you
could explain how to add the debug privilege, that would be great.
OK, this being Windows security, there's a couple
of hoops to jump through, but nothing too bad.
<code>
import win32api
import win32security as sec
#
# This function is merely window-dressing
# to make it easier to see whether the
# code has worked or not.
#
def priv_status (hToken, priv):
for p, status in sec.GetTokenInformation (
hToken,
sec.TokenPrivileges
):
if p == priv:
if status == 0:
return "disabled"
else:
return "enabled"
else:
return "disabled"
process = win32api.GetCurrentProcess ()
token_access_flags = sec.TOKEN_ADJUST_PRIVILEGES | sec.TOKEN_QUERY
hToken = sec.OpenProcessToken (process, token_access_flags)
debug_priv = sec.LookupPrivilegeValue (None, sec.SE_DEBUG_NAME)
print "Debug is", priv_status (hToken, debug_priv)
privs = [(debug_priv, sec.SE_PRIVILEGE_ENABLED)]
sec.AdjustTokenPrivileges (hToken, 0, privs)
print "Debug is", priv_status (hToken, debug_priv)

Just out of curiosity, is there a reason a python module like os
couldn't have a universal terminateProcess type function, that works
on all systems? Something like os.listdir seems to work really well
everywhere. Maybe killing processes is too complicated for this?
Not to say that there could never be one, but I suspect
that the difference of APis and the number of corner
cases makes it a daunting task for maintenance. The
code would have to work on every platform Python works
on -- which is no small number -- and would have to be
maintained across the many and varied changes on each
of those platforms.
Still, if you think you're in with a chance, go ahead
and offer :)
Let us know if the DEBUG priv thing works or not.
