NAME

6       wcsnlen - determine the length of a fixed-size wide-character string
7

SYNOPSIS

9       #define _GNU_SOURCE
10       #include <wchar.h>
11
12       size_t wcsnlen(const wchar_t *s, size_t maxlen);
13

DESCRIPTION

15       The   wcsnlen()  function  is  the  wide-character  equivalent  of  the
16       strnlen(3) function.  It returns the number of wide-characters  in  the
17       string  pointed to by s, not including the terminating L'\0' character,
18       but at most maxlen.  In doing this, wcsnlen() looks only at  the  first
19       maxlen wide-characters at s and never beyond s+maxlen.
20

RETURN VALUE

22       The  wcsnlen() function returns wcslen(s), if that is less than maxlen,
23       or maxlen if there is no L'\0' character among the  first  maxlen  wide
24       characters pointed to by s.
25

CONFORMING TO

27       This function is a GNU extension.
