Why are you not using _T_MAX for all these array-size?
Just a nit: I express this way that wbuf should have the same size as titles. Similarly, wlen and buf size depends on wbuf size. Some might argue it's also more readable. When the reader sees _T_MAX she has to check what it is bound to. This makes the code a tad more resistant in case we changed the size of titles without using _T_MAX. We never know. -- Pierre Neidhardt The good die young -- because they see it's no use living if you've got to be good. -- John Barrymore
