wcsnlen - determine the length of a fixed-size wide-character string

The wcsnlen() function is the wide-character equivalent of the strnlen(3) function. It returns the number of wide-characters in the string pointed to by s, not including the terminating null wide charac- ter L'\0', but at most maxlen wide characters (note: this parameter is not a byte count). In doing this, wcsnlen() looks at only 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 null wide character among the first maxlen wide characters pointed to by s.

Notes

The wcsnlen() function is provided in glibc since version 2.1.
