Class UdpBindLock

A class that provides a mechanism to ensure that only one instance of a process is running at a time by attempting to bind to a specific UDP port.

This is useful for preventing multiple instances of a script or application from running simultaneously.

Note: The lock is automatically released when the process exits, but it is recommended to call releaseLock explicitly when the lock is no longer needed.

Example usage:

const lock = new ProcessLock({
  udpSocketType: "udp4",
  udpBindPort: 12345,
});

const acquired = await lock.tryAcquireLock();
if (!acquired) {
  console.error("Another instance is already running.");
  process.exit(1);
}

// ... application logic ...

await lock.releaseLock();
