Hi, I haven't posted here before. So, nice to meet you all and hope this isn't off topic :) I was wondering if it is possible at all for one userland application to access another application's memory space. By "userland" I mean non-kernel code... that's the correct term right? I had a program under OS 9 that could be used to do this (mostly to cheat at games :) I understand that under Darwin memory is "protected" and one application can only use its memory space and/or shared memory (which I have no idea about at all). Anyway, my secondary question is: can one application access another's memory? It's possible for one application to make its memory available to be shared. It's also possible for a privileged process to get access to memory of another process (think of how a debugger might work). The answer depends a lot on just what you mean by "can one application access another's memory?" Can you be a bit more descriptive? This email sent to site_archiver@lists.apple.com
