I am not as familiar with the hsearch(3C) functions as well as I am with
the tsearch(3C) (binary tree) functions.  However, with the use of
tsearch, the functions store a pointer to the pointer you give it.  So
in your comparison/search functions, you should make sure that your are
properly dereferencing the pointers.
