man:wmemcmp

WMEMCMP(3) Linux Programmer's Manual WMEMCMP(3)

NAME

     wmemcmp - compare two arrays of wide-characters

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 mem-
     cmp(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].
