Reading/writing from/to multiple locations in one command #23
Description
Hi,
I've been getting back into this sort of stuff a little bit recently, and am making an "information display" of sorts for a game, where I'm hoping to display various information read from memory, ideally at 30 Hz or higher. I don't think I can do that currently if I have a lot of synchronous read commands, so I'm wondering if you agree that a new command with iov-like capabilities would be useful (basically doing what the title says).
If so, I'm not sure what the best implementation would be. In my head right now, I'm imagining something like how process lists are returned currently, where the requester would send something like a pid and amount of records it's going to send, followed by the records themselves. I'm also thinking about the scope of this, as a current use-case for reading memory is pointer path traversal, which you can't do in a single request like this, unless you specifically account for it.
Writing to memory might also be useful, but that then adds length variations.
Lastly, I have a few more questions/things (unable to get ELF loading to work, a few C++ libdebug bugs, am currently porting libdebug to Zig), but am unsure about whether this is the proper place to post them.
btw I'm willing to implement this in a PR if you'd like, just wanted to run it by you first.
Thanks!
