21 The wcscmp() function shall compare the wide-character string pointed
22 to by ws1 to the wide-character string pointed to by ws2.
23
24 The sign of a non-zero return value shall be determined by the sign of
25 the difference between the values of the first pair of wide-character
26 codes that differ in the objects being compared.
27
29 Upon completion, wcscmp() shall return an integer greater than, equal
30 to, or less than 0, if the wide-character string pointed to by ws1 is
31 greater than, equal to, or less than the wide-character string pointed
32 to by ws2, respectively.
