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 char-
       acters pointed to by s.

CONFORMING TO
       This function is a GNU extension.
