NAME

       wcsncmp - compare two fixed-size wide-character strings

SYNOPSIS

       #include <wchar.h>

       int wcsncmp(const wchar_t *s1, const wchar_t *s2, size_t n);

DESCRIPTION

       The  wcsncmp()  function  is  the  wide-character equivalent of the strncmp(3) function.  It compares the
       wide-character string pointed to by s1 and the wide-character string pointed to by s2, but at most n wide
       characters from each string.  In each string, the comparison extends only up to the first occurrence of a
       null wide character (L'\0'), if any.

RETURN VALUE

       The wcsncmp() function returns zero if the wide-character strings at s1 and  s2,  truncated  to  at  most
       length  n,  are equal.  It returns an integer greater than zero if at the first differing position i (i <
       n), the corresponding wide-character s1[i] is greater than s2[i].  It returns an integer less  than  zero
       if at the first differing position i (i < n), the corresponding wide-character s1[i] is less than s2[i].
