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 nulll 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].
