Overview

Package control implements a low-level client for the Tor control spec version 1.

The primary entrypoint is the Conn struct, instantiated with NewConn. This is the low-level layer to the control port of an already-running Tor instance. Most developers will prefer the tor package adjacent to this one for a higher level abstraction over the process and this connection.

Some of this code is lifted from https://github.com/yawning/bulb with thanks.

func (*Conn) HandleNextEvent 

func (c *Conn) HandleNextEvent() error
