Thanks for the feedback, I hope the quality of the software increases
during this review phase.

I rewrote this function, see the following patch version.

I changed this line to "if (ret == 0)".
When I use a not-equal relation I try to put the smaller value on the left
hand side and the bigger one to the right hand side. In this case a range
which is expressed in mathematical notation like 10 < a <= 16 can be written
in C like (10 < a) && (a <= 16).
But it is a different question what people like and what not, so I've changed
that line.

Thanks.
I'm looking forward to receive more comments on the new version of this patch.
