MEMORY_STACKS_REGISTERS.rst

Examing Memory,stack and registers in a simple C program using GDB

The code is a very simple program to add two integers passed as command line arguments and prints a string with the result

Compile using the command below and call the executable with some arguments..

$ gcc -ggdb -o memory_demo memory_demo.c
$ ./memory_demo 32 23

In another separate window lets obtain the process id( pid ) of the program with

$ ps -aux | grep memory_demo

The result should look like

In the linux filesystem the /proc/ contains the runtime information associated with all running processes and thus you should find a directory in this directory with a name corresponding to the process id you obtained above.

Our interest is the maps file which contains the memory layout in virtual memory

$ cat /proc/YOUR_PID/maps
