Linux read write process memory

linux read write process memory

The data segment, which is contiguous (in a virtual sense) with the wd my passport 2tb driver for mac text segment, can be subdivided into initialized data (e.g.
The script below dumps all writeable regions (source : ).

If there is any library or anything else I prefer to have it done in Python (or maybe C).M apt-get install libstdc6-4.3-doc Adv Reply « Previous Thread Next Thread » Bookmarks Bookmarks Posting Permissions You may not post new threads You may not post replies You may not post attachments You may not edit your posts Ubuntu Forums Code of Conduct All times.If an address is unmapped in the process, reading from the corresponding offset in the file returns EIO (Input/output error).I've written a function implementation for this.For example, since the first page in a process is never mapped (so that dereferencing a null pointer fails cleanly rather than unintendedly accessing actual memory reading the first byte of /proc/pid/mem always yield an I/O error.In Linux you can gather a lot of information from files.It's incredible how few information about this topic is easily accessible by common searching methods such as google and.H / for opendir readdir closedir #include sys/stat.
The permissions on /proc/pid/mem (r-) are more liberal than what should be the case.
Therefore I would like to get this info from /proc/kcore (if you know of another way to do this please let me know).
