20 The functionality described on this reference page is aligned with the
21 ISO C standard. Any conflict between the requirements described here
22 and the ISO C standard is unintentional. This volume of POSIX.1‐2017
23 defers to the ISO C standard.
24
25 The wcscmp() function shall compare the wide-character string pointed
26 to by ws1 to the wide-character string pointed to by ws2.
27
28 The sign of a non-zero return value shall be determined by the sign of
29 the difference between the values of the first pair of wide-character
30 codes that differ in the objects being compared.
31
33 Upon completion, wcscmp() shall return an integer greater than, equal
34 to, or less than 0, if the wide-character string pointed to by ws1 is
35 greater than, equal to, or less than the wide-character string pointed
36 to by ws2, respectively.
