Can't seem to get it right: Win NT registry save and load

[Matthias Janes]

Hi I would like in a python script to save a Win NT Registry entry to
a file and load it later -
but it's seems I can't get it right.

win32api.RegSaveKey
RegSaveKey(key, filename, sa)

I could not realy figure out the 3 part (sa )

get always a error about the security rights.

after I saved it how could I load it again?

 Any Help would be real nice.
