yes this code is from debugging keyGetBinary

Yes, i am afraid keyGetBinary does not work in any way :-)

Yes, thats the point. I don't really understand why it is encoded to 
hex-values, but ok. The main reason to use binary, is to have it *not* 
encoded.

Can you post me the code how to read it to get any value back?

Maybe best will be to cut off the encoding for binary values. It does not make 
sense anyway and does not work. Or can you repair that avi?

Yes, but i don't want that, because i want it fast and directly. Of course i 
know that it is possible to use atoi or strtod with strings. But this does 
not solve the problem with keyGetBinary. I dont think we want buggy functions 
in the api :-)
