/sys$common/syshlp/helplib.hlb CC, Run-time functions, wcscmp  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  Compares two wide-character strings.  The function returns an
  integer that indicates if the strings are different and how they
  differ.  Unlike the wcscoll function, wcscmp compares the string
  based on the binary value of each wide character.

  Syntax:

       #include <wchar.h>

       int wcscmp (const wchar_t *wstr_1, const wchar_t wstr_2);
