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
'InitiateSystem Shutdown' function which is from Advapi32.dll as
advertised by Microsoft
http://msdn.microsoft.com/library/de...emshutdown.asp

Thanks,
P

import ctypes
advapi32 = ctypes.oledll.L oadLibrary('Adv api32.dll')
advapi32.Initia teSystemShutdow n Traceback (most recent call last):
File "<interacti ve input>", line 1, in ?
File "C:\Python24\li b\site-packages\ctypes \__init__.py", line 395, in
__getattr__
func = self._OlecallFu ncPtr(name, self)
AttributeError: function 'InitiateSystem Shutdown' not found

Most likely feature by design. What you see in documentation for C
library is not what your C code will actually use. For example when you
write errno in C (that looks like global variable access) it is
actually a call to __thread_safe_e rrno() function.

Have you tried calling InitiateSystemS hutdownA mentioned in the
documentation?

Thanks! This function exists. However,
advapi32.Initia teSystemShutdow nA("", 'This is a test', 30, 1, 1)
returns 0 though. I will need to play with it a bit more...
