PROLOG
       This  manual page is part of the POSIX Programmer's Manual.  The Linux implementation of this interface may differ (consult the correspond-
       ing 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 functionality described on this reference page is aligned with the ISO C standard. Any conflict between the requirements described here
       and the ISO C standard is unintentional. This volume of POSIX.1-2008 defers to the ISO C standard.

       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-charac-
       ter 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.
