FUNCTION
3
        <<wmemcmp>>---compare wide characters in memory
4
 
5
ANSI_SYNOPSIS
6
        #include <wchar.h>
7
        int wmemcmp(const wchar_t *<[s1]>, const wchar_t *<[s2]>, size_t <[n]>);
8
 
9
TRAD_SYNOPSIS
10
        int wmemcmp(<[s1]>, <[s2]>, <[n]>
11
        const wchar_t *<[s1]>;
12
        const wchar_t *<[s2]>;
13
        size_t <[n]>;
14

DESCRIPTION
16
        The <<wmemcmp>> function compares the first <[n]> wide characters of the
17
        object pointed to by <[s1]> to the first <[n]> wide characters of the
18
        object pointed to by <[s2]>. This function is not affected by locale
19
        and all wchar_t values are treated identically. The null wide character
20
        and wchar_t values not corresponding to valid characters are not treated
21
        specially.
22
 
23
        If <[n]> is zero, <[s1]> and <[s2]> must be a valid pointers and the
24
        function behaves as if the two objects compare equal.
25
 
26
RETURNS
27
        The <<wmemcmp>> function returns an integer greater than, equal to,
28
        or less than zero, accordingly as the object pointed to by <[s1]> is
29
        greater than, equal to, or less than the object pointed to by <[s2]>.
30
 
31
PORTABILITY
32
<<wmemcmp>> is ISO/IEC 9899/AMD1:1995 (ISO C).
33
 
34
No supporting OS subroutines are required.
