How do ELF files work?

An ELF file consists of zero or more segments, and describe how to create a process/memory image for runtime execution. When the kernel sees these segments, it uses them to map them into virtual address space, using the mmap(2) system call. In other words, it converts predefined instructions into a memory image.

How do I edit ELF files? 1 Answer Any hexeditor If you know exactly which part of ELF to modify, you can do this. You can parse ELFs to do more complicated logic. To do this, you will need code that will open file or, even better, mmap it.
