PROLOG
       This  manual  page is part of the POSIX Programmer's Manual.  The Linux
       implementation of this interface may differ (consult the  corresponding
       Linux  manual page for details of Linux behavior), or the interface may
       not be implemented on Linux.
NAME
       wcsncmp - compare part of two wide-character strings
SYNOPSIS
       #include <wchar.h>
       int wcsncmp(const wchar_t *ws1, const wchar_t *ws2, size_t n);

DESCRIPTION
       The wcsncmp() function shall compare not  more  than  n  wide-character
       codes  (wide-character codes that follow a null wide-character code are
       not compared) from the array pointed to by ws1 to the array pointed  to
       by ws2.
       The  sign of a non-zero return value shall be determined by the sign of
       the difference between the values of the first pair  of  wide-character
       codes that differ in the objects being compared.
RETURN VALUE
       Upon  successful  completion, wcsncmp() shall return an integer greater
       than, equal to, or less than 0, if the possibly  null-terminated  array
       pointed  to by ws1 is greater than, equal to, or less than the possibly
       null-terminated array pointed to by ws2, respectively.
