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 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].

ATTRIBUTES
   Multithreading (see pthreads(7))
       The wmemcmp() function is thread-safe.

CONFORMING TO
       C99.
