isspace(0) is false so you don't need the *p check.

This assert seems superfluous, you just dereferenced the pointer. Also,
you incremented it just above and also (rightly) assumed it was larger
than ArcPath.

To me that sounds like an argument of why you _can't_ do that.
(You know the Rtl versions of these functions give you an NTSTATUS btw,
right?)

Wine's test framework works okay for unit tests. You can make this an
apitest by just #include'ing the C source file, then it can run on
Testbot.
