# SHM IPC example in Rust

[![Build Status](https://travis-ci.org/mersinvald/rust_shm_ipc.svg?branch=master)](https://travis-ci.org/mersinvald/rust_shm_ipc)

This is an example implementatation of synchronized queue for inter-process communication in shared memory 

for UNIX POSIX-complaint operating systems.

Motivation is to try out rust in unix systems programming

### Goals:

- Safe IPC queue implementation

- Rusty wrappers for pthread sync primitives

### Non-goals:

- Fast IPC queue

- Production-ready code

- Full-featured wrappers

## Library support

Currently this example relies on master branch of rust-lang/libc because of 

Required bindings will be availible in version 0.2.21

## Usage example

``` rust

fn child(queue: Shm>) {

    let pid = process::pid();

    queue.push(pid).unwrap()

}

fn main() {    

    // Create new queue in shm

    let queue = Shm::new(Queue::pshared())

        .unwrap();

    // Spawn processes

    for _ in 0..10 {

        process::spawn(|| {

            child(queue.clone());

        }).unwrap();    

    }

    while let Ok(Some(pid)) = queue.timed_pop(Duration::from_millis(10)) {

        println!("PID {}", pid);

    }   

}

```
