The goal of this repo is to make retriving system informations reside in proc file system easier.
Example
use lpfs::proc::*;
use lpfs::pid::*;
fn main() {
// /proc/stat
println!("{:?}", stat().unwrap());
// /proc/1/stat
println!("{:?}", stat_of(1).unwrap());
}
Interface Design
eminence/procfs is a similar crate with different interface design.
Top-Level Files
Each file is retrived by a function reside in lpfs::proc with same name.
For example, lpfs::proc::cmdline retrive from /proc/cmdline.
Process Directories
It's similar with top-level files, here is an example with stat.
| function | file |
|---|---|
| stat_of(pid) | /proc/[pid]/stat |
| stat_self() | /proc/self/stat |
| stat_of_task(pid, tid) | /proc/[pid]/task/[tid]/stat |
| stat_self_task(tid) | /proc/self/task/[tid]/stat |
These functions reside in lpfs::pid
