The spelling of "__frank__", combined with his question,
causes me to wonder if __frank__ is reading system headers
to find examples of good code.

So, I will advise that
identifiers in system headers
use reserved naming conventions,
such as two leading __underscores,
with the implication being that
the programmer can and should avoid naming conflicts
by not using identifiers begining with two uderscores.

The rules for when you should and shouldn't begin
identifiers with _underscores are complicated enough,
so that when writing C code, it's simplest to remember
just not to begin any identifiers with any underscores.

What you can *do*. It often happens that you don't know what you can do and
what you can't until you try doing it. Sometimes you think the problem is
simple but when you start working on it, you change the opinion. The
opposite is also possible. Attempting to solve problems tells you what and
how you can do and tells you what you should do about the things that you
can't...

Hi

Proper English please. Try to make the 1st character of a sentence in
capitals. Get your keyboard repaired. There seems to be something wrong
with the dot ('.') key. It alwyas seems to get pressed thrice.

As for coming to the problem, try and solve it yourself. Please show us
what you attempted and then one of the members would be able to help
you further.

Thanks and have a wonderfuld day.
