WCSNCMP(3)                 Linux Programmer's Manual                WCSNCMP(3)

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  ex-
       tends 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 inte-
       ger 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].
