Internals of Dynamic cast

[Sarath]

Hi All,

How dynamic_cast is implemented in C++? I'm asking it to know how much
overhead it really cause for the program. Could you please put some
light on this?

As you noted, it's implementation dependent. Therefore you need to ask
in a newsgroup dedicated to your compiler. See

A little more explanation on my previous answer.

Per the welcome message, this newsgroup is for discussion of the C++
language as defined by ISO/IEC 14882.

The ISO Standard specified *what* a conforming implemntation must (and
may) do. It provides no specifics on *how* said implementation does it.

If you're studying software development, essentially, this says that
ISO/IEC 14882 is the *REQUIREMENTS*. As you should know, there are
often many ways to implement a given set of requirements. The
implementation doesn't matter so long as the requirements are met.
