scanmem - a ptrace() toy

,

I had an odd requirement for a project I'm correctly working on, I needed to isolate the position of an integer in a executing binary. I had no source, no symbols, and due to the nature of the program, analysis was difficult.

It didnt take long to write a tool to do this, and it was kinda fun, so I'm releasing it. I doubt there are many practical applications, but hey, its still interesting to play with. It currently has a lot of limitations (eg, can only search for dwords), but maybe I'll complete it at some point. You can download it here

update: bumped to version 0.02, applied patch from a reader and included a quick manpage.
