Understanding Stack Frames: Caller Return Addresses and Saved Registers

This article explores the structure of stack frames in programming, focusing on caller return addresses and the significance of saved registers, such as EBP and EBX. A stack frame is essential for function calls, enabling the proper return to the calling function and maintaining local variable integrity. We will dissect a specific stack frame layout and elucidate how buffers and parameters are organized, crucial for understanding low-level programming, debugging, and optimizing application performance.
