const function??

[franco ziade]

what does this declaration mean?

void function_name() const
{}

This means that the function is constant? what is the implication?

Thanks

It means you have broken code. Did you even try to compile it?

laptop ~ # gcc -Wall -W -O2 -c test.c
test.c: In function `function_name':
test.c:2: error: parse error before '{' token

I mean you might as well ask what

for_lots_of_items (int i = 0 through 3; while i < fourteen; add to i)
display me i please;

means...

Are you sure this is supposed to be C and not C++? If it is C++
then you're in the wrong group, please ask in comp.lang.c++. In
C this function declaration is a syntax error.

Nothing. Parse error.

You are probably reading C++ code.
It looks like a member function definition
taken out of the context of the class definition.

What's going on here? What Franco Ziade wrote was:

What you're "citing" has three lines that never were in the post by
Franco Ziade and of the rest you have "edited" one line. So why are
you (again) "citing" something that has never been posted?

If you look carefully, you'll see that ERT correctly marked the lines
he added. In this followup, the OP's line is marked with ">>>", and
the added lines with ">>" (though the original line didn't have the
"{ }" that ERT added to it). He could have been clearer about what he
was doing, though.

We must do something. This is something. Therefore, we must do this.

Yes, I was ready to castigate also. However on NS 4.7x quoted
material is in a different typeface than new material, so things
stand out better. I guess ERT does so many trollish things that we
are overly ready to discover another. Every time he shows signs of
reforming he seems to fall off the wagon again. But this is not a
fall :-)

This means you expect us to read your programming manual for you.

Sorry, I apologize to ERT on the count of adding lines. I don't on
the count of editing lines he's citing (there never was a 'void' in
the original post).
