DESCRIPTION

14       The wcslen() function is the wide-character equivalent of the strlen(3)
15       function.  It  determines  the  length  of  the  wide-character  string
16       pointed to by s, excluding the terminating null wide character (L'\0').
17

RETURN VALUE

19       The wcslen() function returns the number of wide characters in s.
