port-utils-0.2.1.0: Utilities for creating and waiting on ports

Network.Socket.Free

Synopsis

# Documentation

Open a TCP socket on a random free port. This is like warp's openFreePort.

Since 0.0.0.1

Open a TCP socket, get its port and close the socket. Useful when you have an external service that needs a fresh port.

There is a small race condition present: It's possible to get a free port only for it to be bound by some other process or thread before used

Since 0.2.1
