#include <connection_st.h>
Description of a connection to another host or process, and associated data.
A connection is named based on what it's connected to – an "OR connection" has a Tor node on the other end, an "exit connection" has a website or other server on the other end, and an "AP connection" has an application proxy (and thus a user) on the other end.
Every connection has a type and a state. Connections never change their type, but can go through many state changes in their lifetime.
Every connection has two associated input and output buffers. Listeners don't use them. For non-listener connections, incoming data is appended to conn->inbuf, and outgoing data is taken from conn->outbuf. Connections differ primarily in the functions called to fill and drain these buffers.

| unsigned int active_on_link |
True iff we're currently able to read on the linked conn, and our read_event should be made active with libevent.

| tor_addr_t addr |
IP address on the internet of this connection's peer, usually.
This address may come from several sources. If this is an outbound connection, it is the address we are trying to connect to–either directly through s, or via a proxy. (If we used a proxy, then getpeername(s) will not give this address.)
For incoming connections, this field is the address we got from getpeername() or accept(), as updated by any proxy that we are using (for example, an ExtORPort proxy).
For listeners, this is the address we are trying to bind to.
If this connection is using a unix socket, then this address is a null address, and the real address is in the address field.
If this connection represents a request made somewhere other than via TCP (for example, a UDP dns request, or a controller resolve request), then this address is the address that originated the request.
TECHNICAL DEBT:
There are a few places in the code that modify this address, or use it in other ways that we don't currently like. Please don't add any more!
The misuses of this field include:
