SYNOPSIS
#include <wchar.h>
int wmemcmp(const wchar_t *s1, const wchar_t *s2, size_t n);
DESCRIPTION
The
wmemcmp()
function is the wide-character equivalent of the
memcmp(3)
function.
It compares the
n
wide-characters starting at
s1
and the
n
wide-characters starting at
s2.
RETURN VALUE
The
wmemcmp()
function returns
zero if the wide-character arrays of size
n
at
s1
and
s2
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].
