## Connection Signals
### Signal List
* [online](#online)
* [offline](#offline)
* [signing-on](#signing-on)
* [signed-on](#signed-on)
* [autojoin](#autojoin)
* [signing-off](#signing-off)
* [signed-off](#signed-off)
* [connection-error](#connection-error)
### Signal Details
#### online
```c
void user_function(gpointer user_data);
```
Emitted when the first connection has connected when all connections were
previously not connected.
**Parameters:**
**user_data**
: user data set when the signal handler was connected.
----
#### offline
```c
void user_function(gpointer user_data);
```
Emitted when the last connected connection has disconnected.
**Parameters:**
**user_data**
: user data set when the signal handler was connected.
----
#### signing-on
```c
void user_function(PurpleConnection *gc, gpointer user_data);
```
Emitted when a connection is about to sign on.
**Parameters:**
**gc**
: The connection that is about to sign on.
**user_data**
: user data set when the signal handler was connected.
----
#### signed-on
```c
void user_function(PurpleConnection *gc, gpointer user_data);
```
Emitted when a connection has signed on.
**Parameters:**
**gc**
: The connection that has signed on.
**user_data**
: user data set when the signal handler was connected.
----
#### autojoin
```c
gboolean user_function(PurpleConnection *gc, gpointer user_data);
```
Emitted when a connection has signed on, after the signed-on signal, to signal
UIs to autojoin chats if they wish. UIs should connect to this with
`PURPLE_SIGNAL_PRIORITY_HIGHEST` to allow plugins to block this signal before
the UI sees it and then re-emit it later.
**Parameters:**
**gc**
: The connection that has signed on.
**user_data**
: user data set when the signal handler was connected.
**Returns:**
`TRUE` if the signal was handled or `FALSE` otherwise. In practice, the return
value is irrelevant, as it really only exists so plugins can block the UI's
autojoin.
----
#### signing-off
```c
void user_function(PurpleConnection *gc, gpointer user_data);
```
Emitted when a connection is about to sign off.
**Parameters:**
**gc**
: The connection that is about to sign off.
**user_data**
: user data set when the signal handler was connected.
----
#### signed-off
```c
void user_function(PurpleConnection *gc, gpointer user_data);
```
Emitted when a connection has signed off.
**Parameters:**
**gc**
: The connection that has signed off.
**user_data**
: user data set when the signal handler was connected.
----
#### connection-error
```c
void user_function(PurpleConnection *gc,
PurpleConnectionError err,
const gchar *desc,
gpointer user_data);
```
Emitted when a connection error occurs, before `"signed"`-off.
**Parameters:**
**gc**
: The connection on which the error has occurred.
**err**
: The error that occurred.
**desc**
: A description of the error, giving more information.
**user_data**
: user data set when the signal handler was connected.
