PARAMETERS
  s1  Specifies the wide-character string being searched.

  s2  Specifies the wide-character substring to be located.

DESCRIPTION
  The wcsstr() function locates the first occurrence in the wide-character
  string pointed to by the s1 parameter of the sequence of wide characters in
  the wide-character string pointed to by the s2 parameter, excluding the
  terminating null wide character.

RETURN VALUES
  Upon successful completion, the wcsstr() function returns a pointer to the
  located wide-character substring or a null pointer when the substring is
  not found.  If the s2 parameter points to a wide-character substring having
  0 (zero) length, the wcsstr() function returns the entire wide-character
  string pointed to by parameter s1.

  [Digital] On error, the function returns a null pointer.
