## Description

The TpAccountManager object is used to communicate with the Telepathy AccountManager service.

A new TpAccountManager object can be created with `tp_account_manager_dup()`.

To list the existing valid accounts, the client should first prepare the `TP_ACCOUNT_MANAGER_FEATURE_CORE` feature using `tp_proxy_prepare_async()`, then call `tp_account_manager_dup_valid_accounts()`.

The "account-validity-changed" signal is emitted to notify of the validity of an account changing. New accounts are also indicated by the emission of this signal on an account that did not previously exist. (The rationale behind indicating new accounts by an account validity change signal is that clients interested in this kind of thing should be connected to this signal anyway: an account having just become valid is effectively a new account to a client.)

The "account-removed" signal is emitted when existing accounts are removed.

## Details

### struct TpAccountManager

    struct TpAccountManager;

The Telepathy Account Manager stores real-time communication accounts and their configuration, places accounts online on request, and manipulates accounts' presence, nicknames and avatars.

TpAccountManager is the "top level" object, its "factory" will be propagated to all other objects like TpAccountManager -> TpAccount -> TpConnection -> TpContact and TpChannel. This means that desired features set on that factory will be prepared on all those objects.

Since 0.7.32

### struct TpAccountManagerClass

    struct TpAccountManagerClass {
    };

The class of a TpAccount.

### tp_account_manager_new ()

    TpAccountManager *  tp_account_manager_new              (TpDBusDaemon *bus_daemon);

Convenience function to create a new account manager proxy. The returned TpAccountManager is not guaranteed to be ready on return.

Use `tp_account_manager_dup()` instead if you want an account manager proxy on the starter or session bus (which is almost always the right thing for Telepathy).

`bus_daemon` : | Proxy for the D-Bus daemon
Returns : | a new reference to an account manager proxy

### tp_account_manager_new_with_factory ()

    TpAccountManager *  tp_account_manager_new_with_factory (TpSimpleClientFactory *factory);

Convenience function to create a new account manager proxy. The returned TpAccountManager is not guaranteed to be ready on return.

Should be used only by applications having their own TpSimpleClientFactory subclass. Usually this should be done at application startup and followed by a call to `tp_account_manager_set_default()` to ensure other libraries/plugins will use this custom factory as well.

`factory` : | a TpSimpleClientFactory
Returns : | a new reference to an account manager proxy

### tp_account_manager_init_known_interfaces ()

    void                tp_account_manager_init_known_interfaces
                                                            (void);

Ensure that the known interfaces for TpAccountManager have been set up. This is done automatically when necessary, but for correct overriding of library interfaces by local extensions, you should call this function before calling `tp_proxy_or_subclass_hook_on_interface_add()` with first argument `TP_TYPE_ACCOUNT_MANAGER`.

Since 0.7.32

### tp_account_manager_set_default ()

    void                tp_account_manager_set_default      (TpAccountManager *manager);

Define the TpAccountManager singleton that will be returned by `tp_account_manager_dup()`.

This function may only be called before the first call to `tp_account_manager_dup()`, and may not be called more than once. Applications which use a custom TpSimpleClientFactory and want the default TpAccountManager to use that factory should call this after calling `tp_account_manager_new_with_factory()`.

Unlike `tp_account_manager_dup()`, this function will keep an internal reference to `manager`, so it will never be destroyed.

Note that `manager` must use the default TpDBusDaemon as returned by `tp_dbus_daemon_dup()`

`manager` : | a TpAccountManager

Since 0.15.5

### tp_account_manager_can_set_default ()

    gboolean            tp_account_manager_can_set_default  (void);

Check if `tp_account_manager_set_default()` has already successfully been called.

Returns : | `TRUE` if `tp_account_manager_set_default()` has already successfully been called in this process, `FALSE` otherwise.

Since 0.19.6

### tp_account_manager_dup ()

    TpAccountManager *  tp_account_manager_dup              (void);

Returns an account manager proxy on the D-Bus daemon on which this process was activated (if it was launched by D-Bus service activation), or the session bus (otherwise).

The returned TpAccountManager is cached; the same TpAccountManager object will be returned by this function repeatedly, as long as at least one reference exists. Note that the returned TpAccountManager is not guaranteed to be ready on return.

Returns : | an account manager proxy on the starter or session bus, or `NULL` if it wasn't possible to get a dbus daemon proxy for the appropriate bus. [transfer full]

Since 0.9.0

### tp_account_manager_create_account_async ()

    void                tp_account_manager_create_account_async
                                                            (TpAccountManager *manager,
                                                             const gchar *connection_manager,
                                                             const gchar *protocol,
                                                             const gchar *display_name,
                                                             GHashTable *parameters,
                                                             GHashTable *properties,
                                                             GAsyncReadyCallback callback,
                                                             gpointer user_data);

Requests an asynchronous create of an account on the account manager `manager`. When the operation is finished, `callback` will be called. You can then call `tp_account_manager_create_account_finish()` to get the result of the operation.

`callback` will only be called when the newly created TpAccount has the `TP_ACCOUNT_FEATURE_CORE` feature ready on it, so when calling `tp_account_manager_create_account_finish()`, one can guarantee this feature will be ready.

It is usually better to use TpAccountRequest instead, particularly when using high-level language bindings.

`manager` : | a TpAccountManager
`connection_manager` : | the name of a connection manager
`protocol` : | the name of a protocol
`display_name` : | the display name for the account
`parameters` : | parameters for the new account. [element-type utf8 GObject.Value][transfer none]
`properties` : | properties for the new account. [element-type utf8 GObject.Value][transfer none]
`callback` : | a callback to call when the request is satisfied
`user_data` : | data to pass to `callback`

Since 0.9.0

### tp_account_manager_create_account_finish ()

    TpAccount *         tp_account_manager_create_account_finish
                                                            (TpAccountManager *manager,
                                                             GAsyncResult *result,

Finishes an async create account operation, and returns a new TpAccount object, with the `TP_ACCOUNT_FEATURE_CORE` feature ready on it.

The caller must keep a ref to the returned object using `g_object_ref()` if it is to be kept beyond the lifetime of `result`.

`manager` : | a TpAccountManager

### Warning

`tp_account_manager_ensure_account` is deprecated and should not be used in newly-written code. New code should use `tp_simple_client_factory_ensure_account()` instead.

Lookup an account in the account manager `manager`. If the desired account has already been ensured then the same object will be returned, otherwise it will create a new TpAccount and add it to `manager`. As a result, if `manager` thinks that the account doesn't exist, this will still add it to `manager` to avoid races. Note that the returned TpAccount is not guaranteed to be ready on return.

The caller must keep a ref to the returned object using `g_object_ref()` if it is to be kept.

`manager` : | a TpAccountManager
`path` : | the object path for an account
Returns : | a new TpAccount at `path`, or `NULL` if `path` is not a valid account path. [transfer none]

### Warning

`tp_account_manager_get_valid_accounts` is deprecated and should not be used in newly-written code. Since 0.19.9. New code should use `tp_account_manager_dup_valid_accounts()` instead.

Returns a newly allocated GList of valid accounts in `manager`. The list must be freed with `g_list_free()` after used. None of the accounts in the returned list are guaranteed to be ready.

Note that the TpAccounts in the returned GList are not reffed before returning from this function. One could ref every item in the list like the following example:

    1
    2
    3
    GList *accounts;
    account = tp_account_manager_get_valid_accounts (manager);
    g_list_foreach (accounts, (GFunc) g_object_ref, NULL);

The returned TpAccounts are guaranteed to have `TP_ACCOUNT_FEATURE_CORE` prepared, along with all features previously passed to `tp_simple_client_factory_add_account_features()`.

The list of valid accounts returned is not guaranteed to have been retrieved until `TP_ACCOUNT_MANAGER_FEATURE_CORE` is prepared (`tp_proxy_prepare_async()` has returned). Until this feature has been prepared, an empty list (`NULL`) will be returned.

Returns a newly allocated GList of reffed valid accounts in `manager`. The list must be freed with `g_list_free_full()` and `g_object_unref()` after used.

The returned TpAccounts are guaranteed to have `TP_ACCOUNT_FEATURE_CORE` prepared, along with all features previously passed to `tp_simple_client_factory_add_account_features()`.

The list of valid accounts returned is not guaranteed to have been retrieved until `TP_ACCOUNT_MANAGER_FEATURE_CORE` is prepared (`tp_proxy_prepare_async()` has returned). Until this feature has been prepared, an empty list (`NULL`) will be returned.

Gets the most available presence over all accounts in `manager`. This function does not average presences across all accounts, but it merely finds the "most available" presence. As a result, there is a guarantee that there exists at least one account in `manager` with the returned presence.

If no accounts are enabled or valid the output will be (`TP_CONNECTION_PRESENCE_TYPE_OFFLINE`, "offline", "").

Since 0.17.5, if the only connected accounts does not implement `TP_IFACE_CONNECTION_INTERFACE_SIMPLE_PRESENCE`, the output will be (`TP_CONNECTION_PRESENCE_TYPE_AVAILABLE`, "available", "").

The return value of this function is not guaranteed to have been retrieved until `tp_proxy_prepare_async()` has finished; until then, the value will be the same as if no accounts are enabled or valid.

`manager` : | a TpAccountManager
`status` : | a string to fill with the actual status. [out][transfer full]

Iterates through the accounts in `manager` and requests the presence (`type`, `status` and `message`). Note that the presence requested here is merely a request, and if might not be satisfiable.

You can find the most available presence across all accounts by calling `tp_account_manager_get_most_available_presence()`.

Setting a requested presence on all accounts will have no effect until `tp_proxy_prepare_async()` (or the older `tp_account_manager_prepare_async()`) has finished.

### tp_account_manager_enable_restart ()

    void                tp_account_manager_enable_restart   (TpAccountManager *manager);

Enable autostarting the account manager D-Bus service. This means that the account manager will be restarted if it disappears from the bus.

`manager` : | a TpAccountManager

### TP_ACCOUNT_MANAGER_FEATURE_CORE

    #define             TP_ACCOUNT_MANAGER_FEATURE_CORE

Expands to a call to a function that returns a quark for the "core" feature on a TpAccountManager.

When this feature is prepared, the list of accounts have been retrieved and are available for use, and change-notification has been set up. Additionally, the TpAccount objects for accounts which existed at the time this feature was prepared will have TP_ACCOUNT_FEATURE_CORE prepared, but TpAccount objects subsequently announced by "account-validity-changed" are not guaranteed to have this feature prepared. In practice, this means that the accounts returned by calling `tp_account_manager_dup_valid_accounts()` immediately after successfully calling `tp_proxy_prepare_finish()` on the TpAccountManager will have TP_ACCOUNT_FEATURE_CORE prepared, but later calls to that function do not have the same guarantee.

One can ask for a feature to be prepared using the `tp_proxy_prepare_async()` function, and waiting for it to callback.

### Warning

`tp_account_manager_prepare_async` is deprecated and should not be used in newly-written code. since 0.15.6, use `tp_proxy_prepare_async()` instead.

Requests an asynchronous preparation of `manager` with `TP_ACCOUNT_MANAGER_FEATURE_CORE`, plus any features specified by `features`. When the operation is finished, `callback` will be called. You can then call `tp_account_manager_prepare_finish()` to get the result of the operation.

If `NULL` is given to `callback`, then no callback will be called when the operation is finished. Instead, it will simply set `features` on `manager`. Note that if `callback` is `NULL`, then `user_data` must also be `NULL`.

In version 0.11.3 or later, this is equivalent to calling `tp_proxy_prepare_async()` with the same arguments.

`in_Display_Name` : | Used to pass an 'in' argument: The initial value of the new account's <tp:dbus-ref namespace="org.freedesktop.Telepathy.Account">DisplayName</tp:dbus-ref> property. The account manager SHOULD modify this to make it unique if an Account already exists with the same display name, for instance by appending a number or the 'account' parameter. Account manager implementations SHOULD accept an empty string, but account editing user interfaces should avoid passing an empty string for this parameter. <tp:rationale> <p>The account creation UI may ask the user for a name for the new account. If the author of the UI chooses not to do this, the account creation UI is better able to suggest a default display name because it has protocol-specific knowledge which the account manager does not.</p> <p>The account manager always knows the complete list of accounts so it can easily tell whether it should append something to the display name to avoid presenting two identically-named accounts to the user.</p> </tp:rationale>
`in_Parameters` : | Used to pass an 'in' argument: Initial parameter values, as would be passed to <tp:dbus-ref namespace="org.freedesktop.Telepathy.ConnectionManager">RequestConnection</tp:dbus-ref>.
