If the object is resolvable with CreateFile then it doesn't matter if
it's a file, directory, named pipe, or some other miscellaneous thing.
 I templated part 2 after how GetSecurityInfo works (it also ignores
the SE_OBJECT_TYPE), I'm not even sure what type of object you'd call
the function with where it might matter.
