+/***
+*wcscmp - compare two wide character strings, returning less than, equal to,
+*       or greater than
+*
+*Purpose:
+*       WCSCMP compares two wide character strings and returns an integer
+*       to indicate whether the first is less than the second, the two are
+*       equal, or whether the first is greater than the second.
+*
+*       Comparison is done byte by byte on an UNSIGNED basis, which is to
+*       say that Null (0) is less than any other character (1-0xffff).
+*
+*Entry:
+*       const wchar_t * src - string for left-hand side of comparison
+*       const wchar_t * dst - string for right-hand side of comparison
+*
+*Exit:
+*       returns -1 if src <  dst
+*       returns  0 if src == dst
+*       returns +1 if src >  dst
+*
+*Exceptions:
