Enumeration Type Documentation

◆ PurpleConnectionError

enum PurpleConnectionError

Possible errors that can cause a connection to be closed.

Since: 2.3.0

Enumerator
PURPLE_CONNECTION_ERROR_NETWORK_ERROR	There was an error sending or receiving on the network socket, or there was some protocol error (such as the server sending malformed data).
PURPLE_CONNECTION_ERROR_INVALID_USERNAME	The username supplied was not valid.
PURPLE_CONNECTION_ERROR_AUTHENTICATION_FAILED	The username, password or some other credential was incorrect. Use PURPLE_CONNECTION_ERROR_INVALID_USERNAME instead if the username is known to be invalid.
PURPLE_CONNECTION_ERROR_AUTHENTICATION_IMPOSSIBLE	libpurple doesn't speak any of the authentication methods the server offered.
PURPLE_CONNECTION_ERROR_NO_SSL_SUPPORT	libpurple was built without SSL support, and the connection needs SSL.
PURPLE_CONNECTION_ERROR_ENCRYPTION_ERROR	There was an error negotiating SSL on this connection, or the server does not support encryption but an account option was set to require it.
PURPLE_CONNECTION_ERROR_NAME_IN_USE	Someone is already connected to the server using the name you are trying to connect with.
PURPLE_CONNECTION_ERROR_INVALID_SETTINGS	The username/server/other preference for the account isn't valid. For instance, on IRC the username cannot contain white space. This reason should not be used for incorrect passwords etc: use PURPLE_CONNECTION_ERROR_AUTHENTICATION_FAILED for that. Todo: This reason really shouldn't be necessary. Usernames and other account preferences should be validated when the account is created.
PURPLE_CONNECTION_ERROR_CERT_NOT_PROVIDED	The server did not provide a SSL certificate.
PURPLE_CONNECTION_ERROR_CERT_UNTRUSTED	The server's SSL certificate could not be trusted.
PURPLE_CONNECTION_ERROR_CERT_EXPIRED	The server's SSL certificate has expired.
PURPLE_CONNECTION_ERROR_CERT_NOT_ACTIVATED	The server's SSL certificate is not yet valid.

PURPLE_CONNECTION_ERROR_CERT_FINGERPRINT_MISMATCH	The server's SSL certificate does not have the expected fingerprint.
PURPLE_CONNECTION_ERROR_CERT_SELF_SIGNED	The server's SSL certificate is self-signed.
PURPLE_CONNECTION_ERROR_CERT_OTHER_ERROR	There was some other error validating the server's SSL certificate.
PURPLE_CONNECTION_ERROR_OTHER_ERROR	Some other error occurred which fits into none of the other categories.

Function Documentation

◆ purple_connection_destroy()

void purple_connection_destroy ( PurpleConnection * gc )

Disconnects and destroys a PurpleConnection.

This function should only be called by purple_account_disconnect() in account.c. If you're trying to sign off an account, use that function instead.

Parameters

gc	The purple connection to destroy.

Deprecated:: As this is internal, we should make it private in 3.0.0.

◆ purple_connection_error()

void purple_connection_error	(	PurpleConnection *	gc,
		const char *	reason
	)

Closes a connection with an error.

Parameters

gc	The connection.
reason	The error text, which may not be `NULL`.

Deprecated:: in favour of purple_connection_error_reason. Calling purple_connection_error(gc, text) is equivalent to calling purple_connection_error_reason(gc, reason, text) where reason is PURPLE_CONNECTION_ERROR_OTHER_ERROR if gc->wants_to_die is TRUE, and PURPLE_CONNECTION_ERROR_NETWORK_ERROR if not. (This is to keep auto-reconnection behaviour the same when using old prpls which don't use reasons yet.)

◆ purple_connection_error_is_fatal()

gboolean purple_connection_error_is_fatal ( PurpleConnectionError reason )

Reports whether a disconnection reason is fatal (in which case the account should probably not be automatically reconnected) or transient (so auto-reconnection is a good idea).

For instance, PURPLE_CONNECTION_ERROR_NETWORK_ERROR is a temporary error, which might be caused by losing the network connection, so purple_connection_error_is_fatal (PURPLE_CONNECTION_ERROR_NETWORK_ERROR) is FALSE. On the other hand, PURPLE_CONNECTION_ERROR_AUTHENTICATION_FAILED probably indicates a misconfiguration of the account which needs the user to go fix it up, so purple_connection_error_is_fatal (PURPLE_CONNECTION_ERROR_AUTHENTICATION_FAILED) is TRUE.

(This function is meant to replace checking PurpleConnection.wants_to_die.)

Returns: TRUE if the account should not be automatically reconnected, and FALSE otherwise.

Since: 2.3.0

◆ purple_connection_error_reason()

void purple_connection_error_reason	(	PurpleConnection *	gc,
		PurpleConnectionError	reason,
		const char *	description
	)

Closes a connection with an error and a human-readable description of the error.

It also sets gc->wants_to_die to the value of purple_connection_error_is_fatal(reason), mainly for backwards-compatibility.

Parameters

gc	the connection which is closing.
reason	why the connection is closing.
description	a non-`NULL` localized description of the error.

Since: 2.3.0

◆ purple_connection_get_account()

PurpleAccount * purple_connection_get_account ( const PurpleConnection * gc )

Returns the connection's account.

Parameters

gc	The connection.

Returns: The connection's account.

◆ purple_connection_get_display_name()

const char * purple_connection_get_display_name ( const PurpleConnection * gc )

Returns the connection's displayed name.

Parameters

gc	The connection.

Returns: The connection's displayed name.

◆ purple_connection_get_password()

const char * purple_connection_get_password ( const PurpleConnection * gc )

Returns the connection's password.

Parameters

gc	The connection.

Returns: The connection's password.

◆ purple_connection_get_protocol_data()

void * purple_connection_get_protocol_data ( const PurpleConnection * connection )

Gets the protocol data from a connection.

Parameters

connection The PurpleConnection.

Returns: The protocol data for the connection.

Since: 2.6.0

◆ purple_connection_get_prpl()

PurplePlugin * purple_connection_get_prpl ( const PurpleConnection * gc )

Returns the protocol plugin managing a connection.

Parameters

gc	The connection.

Returns: The protocol plugin.

Since: 2.4.0

◆ purple_connection_get_state()

PurpleConnectionState purple_connection_get_state ( const PurpleConnection * gc )

Returns the connection state.

Parameters

gc	The connection.

Returns: The connection state.

◆ purple_connection_new()

void purple_connection_new	(	PurpleAccount *	account,
		gboolean	regist,
		const char *	password
	)

This function should only be called by purple_account_connect() in account.c.

If you're trying to sign on an account, use that function instead.

Creates a connection to the specified account and either connects or attempts to register a new account. If you are logging in, the connection uses the current active status for this account. So if you want to sign on as "away," for example, you need to have called purple_account_set_status(account, "away"). (And this will call purple_account_connect() automatically).

Parameters

account	The account the connection should be connecting to.
regist	Whether we are registering a new account or just trying to do a normal signon.
password	The password to use.

Deprecated:: As this is internal, we should make it private in 3.0.0.

◆ purple_connection_new_unregister()

void purple_connection_new_unregister	(	PurpleAccount *	account,
		const char *	password,
		PurpleAccountUnregistrationCb	cb,
		void *	user_data
	)

This function should only be called by purple_account_unregister() in account.c.

Tries to unregister the account on the server. If the account is not connected, also creates a new connection.

Parameters

account	The account to unregister
password	The password to use.
cb	Optional callback to be called when unregistration is complete
user_data	user data to pass to the callback

Deprecated:: As this is internal, we should make it private in 3.0.0.

◆ purple_connection_notice()

void purple_connection_notice	(	PurpleConnection *	gc,
		const char *	text
	)

Displays a connection-specific notice.

Parameters

gc	The connection.
text	The notice text.

◆ purple_connection_set_account()

void purple_connection_set_account	(	PurpleConnection *	gc,
		PurpleAccount *	account
	)

Sets the connection's account.

Parameters

gc	The connection.
account	The account.

◆ purple_connection_set_display_name()

void purple_connection_set_display_name	(	PurpleConnection *	gc,
		const char *	name
	)

Sets the connection's displayed name.

Parameters

gc	The connection.
name	The displayed name.

◆ purple_connection_set_protocol_data()

void purple_connection_set_protocol_data	(	PurpleConnection *	connection,
		void *	proto_data
	)

Sets the protocol data for a connection.

Parameters

connection	The PurpleConnection.
proto_data	The protocol data to set for the connection.

Since: 2.6.0

◆ purple_connection_set_state()

void purple_connection_set_state	(	PurpleConnection *	gc,
		PurpleConnectionState	state
	)

Sets the connection state.

PRPLs should call this and pass in the state PURPLE_CONNECTED when the account is completely signed on. What does it mean to be completely signed on? If the core can call prpl->set_status, and it successfully changes your status, then the account is online.

Parameters

gc	The connection.
state	The connection state.

◆ purple_connection_ssl_error()

void purple_connection_ssl_error	(	PurpleConnection *	gc,
		PurpleSslErrorType	ssl_error
	)

Closes a connection due to an SSL error; this is basically a shortcut to turning the PurpleSslErrorType into a PurpleConnectionError and a human-readable string and then calling purple_connection_error_reason().

Since: 2.3.0

◆ purple_connection_update_progress()

void purple_connection_update_progress	(	PurpleConnection *	gc,
		const char *	text,
		size_t	step,
		size_t	count
	)

Updates the connection progress.

Parameters

gc	The connection.
text	Information on the current step.
step	The current step.
count	The total number of steps.

◆ purple_connections_get_all()

GList * purple_connections_get_all ( void )

Returns a list of all active connections.

This does not include connections that are in the process of connecting.
