I have made a few comments on the implementation below:

Should be in DELAYIMPORTS. We don't want to slow down the loading of all 
applications because of this one uncommon case.

Remove the "almost stub" part of it and just print FIXME's for the parts 
that aren't implemented, otherwise the next person that comes along to 
this function will spend hours trying to work out what isn't 
implemented, if they even realise this function is to blame.

Change this to a FIXME.

This function returns a DWORD error code, not a BOOL.
