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.

ERRORS
