wmemcmp(3C)              Standard C Library Functions              wmemcmp(3C)

NAME
       wmemcmp - compare wide-characters in memory

SYNOPSIS
       #include <wchar.h>

       int wmemcmp(const wchar_t *ws1, const wchar_t *ws2, size_t n);

DESCRIPTION
       The  wmemcmp() function compares the first n wide-characters of the ob‐
       ject pointed to by ws1 to the first n  wide-characters  of  the  object
       pointed  to  by  ws2.  This  function is not affected by locale and all
       wchar_t values are treated identically.  The  null  wide-character  and
       wchar_t  values  not  corresponding to valid characters are not treated
       specially.


       If n is zero, ws1 and ws2 must both be valid pointers and the  function
       behaves as if the two objects compare equal.

RETURN VALUES
       The  wmemcmp()  function  returns an integer greater than, equal to, or
       less than 0, accordingly as the object pointed to  by  ws1  is  greater
       than, equal to, or less than the object pointed to by ws2.

ERRORS
       No errors are defined.
