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

FreeBSD and macOS are supported.
Contributions for improvements and other platforms are welcome.

Documentation

Usage

Add to Cargo.toml

toml [dependencies] sysctl = "0.1.4"

Example

sysctl comes with several examples, see the examples folder.

Run with:

sh $ cargo run --example iterate

Or in a separate crate:

```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);
}

} ```
