14 The wcsncmp() function is the wide-character equivalent of the
15 strncmp(3) function. It compares the wide-character string pointed to
16 by s1 and the wide-character string pointed to by s2, but at most n
17 wide characters from each string. In each string, the comparison
18 extends only up to the first occurrence of a L'\0' character, if any.

21 The wcsncmp() function returns zero if the wide-character strings at s1
22 and s2, truncated to at most length n, are equal. It returns an inte‐
23 ger greater than zero if at the first differing position i (i < n), the
24 corresponding wide-character s1[i] is greater than s2[i]. It returns
25 an integer less than zero if at the first differing position i (i < n),
26 the corresponding wide-character s1[i] is less than s2[i].
