wcsncmp - compare two fixed-size wide-character strings
#include <wchar.h>
int wcsncmp(const wchar_t *s1, const wchar_t *s2, size_t n);
The wcsncmp() function is the wide-character equivalent of the strncmp(3)
function. It compares the wide-character string pointed to by s1 and the
wide-character string pointed to by s2, but at most n wide characters from
each string. In each string, the comparison extends only up to the first
occurrence of a L'\0' character, if any.
The wcsncmp() function returns zero if the wide-character strings at s1 and
s2, truncated to at most length n, are equal. It returns an integer greater
than zero if at the first differing position i (i < n), the corresponding
wide-character s1[i] is greater than s2[i]. It returns an integer less than
zero if at the first differing position i (i < n), the corresponding wide-
character s1[i] is less than s2[i].
