RTTI in C

[Neo]

what is RTTI? and how to implements it? give me sourceful link for
learn and implements it (using standard C mean portable).

Since it's upper case, my money would be on a macro name.

and how to implements it?

#define RTTI 42

If you don't know what it is, why do you want to know how to implement
it? What were you planning on using it for?

Round Trip Time Inconsistency. This is a reference to
the so-called "twin paradox" of Special Relativity, in which
one twin takes a high-speed journey while leaving the other
behind, and upon return discovers that their ages are no
longer the same.

RTTI cannot be implemented in strictly conforming C
because of the requirement that the travelling twin must
move at high speed. The C Standard says nothing about
speed, which is purely an artifact of the implementation
and not a property of the language. Therefore, any attempt
to demonstrate RTTI necessarily involves the implementation-
dependent concept of "speed" and is thus non-portable.

But it could be modelled to a satisfactory degree of accuracy.

There's a time inconsistency between wanting to implement something
before knowing what that something is!

Did I get it? ;-)

#define RTTI 42

I get a similar result, and I'm prepared for changes.

#define RUN 1
#define TIME 5
#define TYPE 12
#define INFORMATION 24
#define R RUN
#define T1 TIME
#define T2 TYPE
#define I INFORMATION
#define RTTI (R + T1 + T2 + I)

1. Don't top-post. Your reply belongs following or interspersed with
properly trimmed quotes.

2. Your answer is incorrect. It does NOT mean that in C, as there is no
such thing.
