There is also another one (mentioned by Coverity) where passing a NULL 
lpNameBuffer and a big enough nSize will crash. I tested that one on 
W2K3 and this also crashes on W2K3.

I didn't test the NULL nSize however.

If time permits I'll add some tests and comments in the case of crashes. 
  If somebody wants to be beat me to it, be my guest.

Out of curiosity, did you find this by visual inspection?
