Thanks.  I've shortened the commit message a bit and pushed this for
you.

Do you want to fix the other issue as well?  The missing declaration of
the variable i, and the incorrect argument list for the error function?

Thanks Florian,

Sure. I'll be happy to do that.
Could you please provide some pointers?

I would suggest to try to get the example to compile.  You will have to
supply a fake OBJECT type and the other stubbed-out things, but after
that, some compilation errors remain, and we should fix those.

Thanks,

Please move the declaration of i into the for statement or to the
start of the function.
