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:
_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 character (Laq\0aq), but at most maxlenwide characters (note: this parameter is not a byte count). In doing this, wcsnlen() looks at only the first maxlenwide characters at sand never beyond s+maxlen.  

RETURN VALUE

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

VERSIONS

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