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'' 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'' character among the first maxlen wide
       characters pointed to by s.

CONFORMING TO
       This function is a GNU extension.
