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 nulll wide character (L'\0'), 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].
