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);

DESCRIPTION
       The  wcsnlen  function is the wide-character equivalent of the strnlen
       function. It returns the	 number	 of  wide-characters  in  the  string
       pointed to by s, not including the terminating L’\0’ character, but at
       most maxlen. In doing this, wcsnlen looks only  at  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 L’\0’ character among the first	 maxlen	 wide
       characters pointed to by s.

CONFORMING TO
       This function is a GNU extension.
