I don't think this post is strictly on-topic, so I apologize in advance. I'm not sure where else to ask this question. I understand that /proc/<pid>/maps gives a list of memory maps for process <pid>: 08048000-080bf000 r-xp 00000000 03:05 645180 /bin/bash 080bf000-080c5000 rw-p 00077000 03:05 645180 /bin/bash 080c5000-080dd000 rwxp 00000000 00:00 0 40000000-40013000 r-xp 00000000 03:05 225830 /lib/ld-2.2.5.so 40013000-40014000 rw-p 00013000 03:05 225830 /lib/ld-2.2.5.so (snip) Hypothetical question: Just suppose, for some reason, I wanted to browse a process's memory maps. To be concrete, suppose I wanted to list the contents of the process's memory between offsets 08048000 and 080bf000. What would the mechanism be for a user space program to do something like this? I think it would start with ptrace() to make this process a child process of the program I wrote to browse memory. Once this process becomes a child process, how can I step through the first memory map, byte by byte? I don't know much about memory, but I'm hoping to learn. :) Thanks!
