pythonCE GetSystemPowerState windows api

[lorenzo.mentaschi]

Hi all,
I need to call GetSystemPowerState windows api from pythonCE, because
I need to know if a windows ce 5 device is in sleep/off status.
I can find this api in ctypes.windll.coredll, but I cannot figure out
how to pass parameters to this procedure: msdn giude (
http://msdn.microsoft.com/en-us/library/ms899319.aspx ) speaks about 3
parameters, of wich 2 are output: a "LPWSTR pBuffer" and a "PDWORD
pFlags". Returned value of the call is an exit status code
rappresenting if call succeded or failed.

I tried to call this api in several ways, but obtained always exit
code 87 (meaning that parameters are wrong) or 122 (meaning "pBuffer"
variable is too small, in this case I passed None as pBuffer, since
I'm interested only in pFlags result).

Have you any idea? Maybe another api or way to perform this simple
task?

Thank you all, Lorenzo
