NAME
wcsncmp - compare two fixed-size wide-character strings
SYNOPSIS
#include <wchar.h>
int wcsncmp(const wchar_t *s1, const wchar_t *s2, size_t n);
DESCRIPTION
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.
RETURN VALUE
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].
CONFORMING TO
