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

SYNOPSIS
       #include <wchar.h>

       size_t wcsnlen(const wchar_t *s, size_t maxlen);

   Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

       wcsnlen():
           Since glibc 2.10:
               _XOPEN_SOURCE >= 700 || _POSIX_C_SOURCE >= 200809L
           Before glibc 2.10:
               _GNU_SOURCE

DESCRIPTION
       The   wcsnlen()  function  is  the  wide-character  equivalent  of  the
       strnlen(3) function.  It returns the number of wide-characters  in  the
       string pointed to by s, not including the terminating null wide charac-
       ter (L'\0'), but at most maxlen wide characters (note:  this  parameter
       is not a byte count).  In doing this, wcsnlen() looks at only the first
       maxlen wide characters at s and never beyond s+maxlen.

RETURN VALUE
       The wcsnlen() function returns wcslen(s), if that is less than  maxlen,
       or  maxlen  if  there  is no null wide character among the first maxlen
       wide characters pointed to by s.

VERSIONS
       The wcsnlen() function is provided in glibc since version 2.1.

ATTRIBUTES
   Multithreading (see pthreads(7))
       The wcsnlen() function is thread-safe.

CONFORMING TO
       POSIX.1-2008.
