Activation Record from C / C++

[Rohit Jog]

Can some one explain the in depth stack management?
Functions are available in almost all languages: when we call a
function one activation record is pushed on to the stack!

How can we access this stack from C / C++?

[Zaman]

To get in-depth explanation of activation-record management get
'compilers' by aho ullman and sethi. C++ and C by design don't allow
you to modify the activation record.

So does that mean from C/C++ i cannot push dummy record on to the
stack?

hi Rohit,
You can push a dummy record onto a stack using a function call, but you cannot manipulate the stack in C++. I mean, like in assembly language programming u know the address of the stack segment and hence can easily work with the stack, modifying the activation records and all.
But C++ doesnot provide a way to do that.

Maybe i'm wrong, but i dont know any technique to access the stack in C++. If somebody knows, i'll really appresiate his/her help.

can we use ASM keyword to include assembly lang instructions into the
code...
it hink it can work..
correct me if i'm wrong

Of course you can - that's what ASM is for? But the OP is asking if
you can use C/C++ to capture the activation record. I am not sure
where this requirement comes from but a short answer is no.

Cheers.
