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