I don't think this will work properly. The returned pointer from CRYPT_LMHash()
will never be passed out to the caller of the function. There should be
probably a function call before the return of the function along the lines
of 

memcpy(hash, buffer, 16);

The question here would also be why use an intermediate buffer at all in the
first place?

Also the use of strcmp() for comparing a hash in the according test seems a
little misplaced to me.
Or is a DES hash guaranteed to never contain 0x00 bytes? It doesn't occur in
the test case so it is not a big problem in this case but principially it
seems not right to me.
