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 extends only up to the first occurrence of a  L'\0'  charac-
       ter, 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].

CONFORMING TO
       C99.
