    Command:

    wcsnlen

    
    
    

    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.
