Get virtual memory maps from another process

This crate provides a function—get_process_maps that returns a Vec of MapRange structs.

This code works on Linux, macOS, and Windows. Each operating system has a different implementation, but the functions and structs for all OSes share the same interface - so this can be used generically across operating systems.

Note: on macOS this requires root access, and even with root will still not work on processes that have System Integrity Protection enabled (anything in /usr/bin for example).

Example

use proc_maps::{get_process_maps, MapRange, Pid};

let maps = get_process_maps(123456 as Pid).unwrap();
for map in maps {
   println!("Filename {:?} Address {} Size {}", map.filename(), map.start(), map.size());
}

proc-maps

This crate supports reading virtual memory maps from another process - and supports Linux, macOS, Windows, and FreeBSD operating systems.

Examples

use proc_maps::get_process_maps;

let maps = get_process_maps(pid)?;
for map in maps {
    println!("Filename {:?} Address {} Size {}", map.filename(), map.start(), map.size());
}

cargo run --example print_maps <PID>
