windows stack

[maros522]

Hello
How/where can I find out the size of stack. Is there any posibility to find out size of stack and heap for one process in c++.
Thank you

I'm sure there is, but on NT-based systems (like XP and Vista) the stack is dynamically handled by the OS -- meaning that it grows as necessary.

Some idea how to get the size of stack in c++. I don't know where to start.

According to the MSDN docs on the /F Compiler Option^[1]

Without this option the stack size defaults to 1 MB.

I remember reading somthing a while ago about calculating the size of the remaining stack space by using the stack pointer and a pointer to the base of the stack. However this used an undocumented feature of the Windows API and I'm having trouble tracking it down.

edit:
All I have found is:

Look at the difference between the current stack pointer and
(PNT_TIB)NtCurrentTeb()->StackLimit.

it may help you on your way to tracking down a 'better' answer.

Also, the C/C++ stack grows dynamically on WIN32.
