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() 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 L'\0' character, 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].

CONFORMING TO
       C99.
