Linux file data deduplication for Node.js
===

Linux VFS provides the FIDEDUPERANGE ioctl to deduplicate byte ranges in multiple files.
This package provides facilities for calling this ioctl.

Usage
---

The package exports the class Deduplicator. For now, this class only provides a single method called
dedupe, which is able to deduplicate a single byte range in two files.

``typescript
import * as fs from "fs";
import { Deduplicator, getStatusInfo } from "@nanobot248/linux-dedupe";

const fd1 = fs.openSync("/path/to/file1").fd;
const off1 = 0;
const len1 = 1024 * 1024;

const fd2 = fs.openSync("/path/to/file2").fd;
const off2 = 0;

const deduplicator = new Deduplicator();
deduplicator.dedupe(fd1, off1, len1, fd2, off2).then((result) => {
console.log("result:", result);
console.log("status: " + getStatusInfo(result.status));
}).catch((err) => {
console.error("error:", err);
});
