Searching a process' memory on Linux

How can I search the memory state of an process in Linux? Specifically I wish to identify certain regions of interest, and peek at them at regular intervals, possibly occasionally poking new values.

I susp开发者_如何学Cect an answer may involve calls to ptrace(), and reading /proc/[pid]/mem, but need more to go on.

I believe you can achieve what you want by parsing /proc/[pid]/maps -- I've used that to diagnose invalid pointers

I've developed some code for the requested functionality.

The module memutil provides process memory region iteration, and python or C memory reading with assistance from the ptrace module, and readmem executable.

If there is any questions, or requests for standalone tools, just ask.

Perhaps using GDB would be an option? You should be able to do things like periodically reading memory using breakpoints.
