wcsnlen - determine the length of a fixed-size wide-character string
size_t wcsnlen(const wchar_t *s, size_t maxlen);
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.
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.
This function is a GNU extension.
