virtual table on g++

[DanielJohnson]

Hi,

I want to study vtable (virtual functions and its behavior) and what
it contains. I am a newbie learning C++ and using g++ compiler.

Can you throw some pointers as to how to use g++ or gdb to look the
contents of vtable ?

Every help is greatly appreciated.

Then you shouldn't care. The details are compiler-specific, and you don't
need to know them for using virtual functions. Actually, the C++ standard
doesn't even mention vtables.

Can you throw some pointers as to how to use g++ or gdb to look the
contents of vtable ?

Someone in gnu.g++.help might.

The following articles describe C++ under the hood. The second article
describes virtual tables.
