Thank you. I didn't realize that option.

Thanks. I'll explore this approach. However, it seems to me that this
approach will require to add an initialization function to my library
(to replace the de/allocation functions), which, a priori, I prefer to
avoid if I could.
I will also explore the other approach suggested by Torbjörn:

Thanks a lot
