Non-existant CUDA device '12(Or 11)' specified in -d option

[Cerunnir]

I have an issue controlling what cards CCminer will use above number 9. Im able to use -d 1,2,3,,,9.

But when I get to 10, it just runs GPU 0.

When I try -d 11 or 12 I get this error:

Non-existant CUDA device '12' specified in -d option

If I just run it without -d at all, it detect all 13 nvidia GPU's and run fine. (Problem with 8+ of the same brand GPU is fixed in windows 10).

To me it seems like CCminer can use all my GPU's fine, but the -d command does not support numbers above 9.

Based on pooler cpuminer 2.3.2 and the tpruvot@github fork

ok, I think I have found the bug

Hello, thanks for looking into it. It does seem to apply to every ccminer out there that ive tested.

Any ways to spread this to the other developers without individually telling them in their github?

The closest thing would be be the bitcointalk forum.
Here for example:

Could you give me a quick description of what the error was? Probably helpful when I make the post. 2017-12-17 5:45 GMT+01:00 KlausT <notifications@github.com>:

The old code was checking the length of the numbers.
If it was longer than one character then you got an error.
The exact code change you can see here:

Now the code isn't checking the length anymore.
