This is not a theoretical C language specifications document. It is a practical primer for the vast majority of real life cases of C usage that are relevant to EFL on todays common architectures. It covers application executables and shared library concepts and is written from a Linux/UNIX perspective where you would have your code running with an OS doing memory mappings and probably protection for you. It really is fundamentally not much different on Android, iOS, OSX or even Windows.
