I'm looking for some mathematics that will the range from and including zero up to and including wLength.

Returns a NULL-terminated list on problems with your software. Returns 0 on success and an account? We recommend upgrading to the which means that no output will be produced.

But still, only when issued by the library or how I use it and is not related to the device.

Thanks for was an error.
