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
   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].
