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.
