How to call functions in Advapi32.dll using ctypes

[Podi]

I have ctypes version 0.9.6 and Python 2.4.2 running on Windows XP
Professional.

When I tried to use some functions in the Advapi32.dll, some functions
are available and some are not. Is this a bug or feature by design?

In the example below, I am trying to examine the
'InitiateSystemShutdown' function which is from Advapi32.dll as
advertised by Microsoft
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/shutdown/base/initiatesystemshutdown.asp

Thanks,
P
