14 The wcsnlen() function is the wide-character equivalent of the
15 strnlen() function. It returns the number of wide-characters in the
16 string pointed to by s, not including the terminating L'\0' character,
17 but at most maxlen. In doing this, wcsnlen() looks only at the first
18 maxlen wide-characters at s and never beyond s+maxlen.
19
21 The wcsnlen() function returns wcslen(s), if that is less than maxlen,
22 or maxlen if there is no L'\0' character among the first maxlen wide
23 characters pointed to by s.

26 This function is a GNU extension.
