Re: Questions about low level programming.

["Diego Jacobi" <jacobidiego gmail com>]

Thanks for your answer, but it really doesnt answer anything.

Of course that i do have a lot to learn, as everybody, and i think that my instructor isnt the right person to ask this kind of questions, but why do you say so, can you be more specific at least?

If no one answer i will think that no one knows the answer and not that it is not possible.

You should probably consult your instructor. It seems like you have a
lot of learning to do that is not specifically about glib.
