I also do not like the "returned value" solution , although I suggested it.
The API functions are much more elegant.

But in the current time constrains I have, the simplest and securest thing I 
see is only this. And it adds only 2 assembler instructions overhead (to test 
the returned value).

Thanks for the help.
