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 null wide character (Laq\0aq), 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].
