I did some net search, and I did found volatile variables, that are like you
say, but I also found volatile
functions that are functions that do not return, just like it was said. But I
did not try it.
I find quite hard to use search engines to find "c--" because they seems not
to recognize the - char and
give results with c- or c rather than c--. So if someone have the link, I'd
appreciate to have it. Or just give
me the name of a search engine that handle "c--" correctly.
