NAME

       wmemcmp - compare two arrays of wide-characters

LIBRARY

       Standard C library (libc, -lc)

SYNOPSIS

       #include <wchar.h>

       int wmemcmp(const wchar_t s1[.n], const wchar_t s2[.n], 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].
