This crate provides a safe interface for reading and writing information to the kernel using the sysctl interface.

Currently only developed and tested on FreeBSD.
Contributions for improvements and other platforms are welcome.

Documentation

Since the crate only builds on FreeBSD documentation is not available on https://docs.rs/sysctl

Available here: https://johalun.github.io/sysctl-rs/sysctl/index.html

or, to generate documentation locally do: shell $ git clone https://github.com/johalun/sysctl-rs && cd sysctl-rs $ cargo doc $ firefox target/doc/sysctl/index.html

Usage

Add to Cargo.toml

toml [dependencies] sysctl = "0.1.0"

Example

```rust extern crate sysctl;

fn main() { let ctl = "kern.osrevision"; let d: String = sysctl::description(ctl).unwrap(); println!("Description: {:?}", d);

let val_enum = sysctl::value(ctl).unwrap();
if let sysctl::CtlValue::Int(val) = val_enum {
    println!("Value: {}", val);
}

} ```
