Our initial goal in this chapter was to provide an overview of the memory structure of a process in a Unix-like operating system. As we have covered a lot in this chapter, take a minute to read through what we've been through, as you should now feel comfortable in understanding what we have accomplished:
- We described the dynamic memory structure of a running process as well as the static memory structure of an executable object file.
- We observed that the static memory layout is located inside the executable object file and it is broken into pieces which are called segments. We found out that the Text, Data, and BSS segments are part of the static memory layout.
- We saw that the Text segment or Code segment is used to store the machine-level instructions meant to be executed when a new process is spawned out of the current executable object file.
- We saw that the BSS segment is used to store global variables that are either uninitialized or set to...
