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)

Regards

Hi, I wrote a few classes recently and am writing a small GC implementation for C++. I will be implementing my own gc_ptr type maintain a list where I'll store pointers to allocated memory. I was wondering if it is possible to identify objects during runtime via RTTI because I don't want to be doing: gc_ptr<int>::doGC(); gc_ptr<double>::doGC();

Hello there, I would like to know what overheads there are to think of when using RTTI. I understand that enabling RTTI increases the sizes of the classes, but not the objects themselves. This doesn't sound too bad. What I'm worried about is whether there is a general performance overhead caused by enabling RTTI, such as enabling exceptions makes a C++ program slower even when there are no exceptions actually used. Are there similar...

Hey all, I know that dynamic_cast<> takes some time, but , for instance, is there a memoy cost associated in with it? Does it have to maintain a table in memory, thus bloating the runtime ram needs of my dll? Does it bloat the actual download size - would my dll be smaller without it? thanks - I'm using rtti in some instances, but I jsut want to know if it's costing me hundreds of K in extra download. -denny-

I'm trying to work out a design for dynamically determining file types, and for generating new files of a given type. I'm curious to know what others think of my current strategy. Is it "so einfach wie möglich machen, aber nicht einfacher" or "Rube Goldberg"?

Hi Friends, I have a question about RTTI. 1) In C++ we have vptr pointing to vtables which helps to make use of pointer as polymorphic entities. 2) Without knowing object type I can call methods of object using those pointers. So in which case RTTI is needed? ( Why I need to know my object type?) Regards,

I'm studying the RTTI, and my current work is concern for how to get the self-defined type at runtime, that's exactly what the RTTI does. I mean, in my application, I built several self-defined data types, so I have to implement the RTTI by myself. I need a simple and effective example to help me decide how to design. Can someon help me?
