## Details

### TpConnectionManagerListCb ()

    void                (*TpConnectionManagerListCb)        (TpConnectionManager * const *cms,
                                                             gsize n_cms,
                                                             const GError *error,
                                                             gpointer user_data,
                                                             GObject *weak_object);

Signature of the callback supplied to `tp_list_connection_managers()`.

Since 0.7.26, `tp_list_connection_managers()` will wait for each TpConnectionManager to become ready, so all connection managers passed to `callback` will be ready (`tp_connection_manager_is_ready()` will return `TRUE`) unless an error occurred while launching that connection manager.

`cms` : | `NULL`-terminated array of TpConnectionManager (the objects will be unreferenced and the array will be freed after the callback returns, so the callback must reference any CMs it stores a pointer to), or `NULL` on error
`n_cms` : | number of connection managers in `cms` (not including the final `NULL`)
`error` : | `NULL` on success, or an error that occurred
`user_data` : | user-supplied data
`weak_object` : | user-supplied weakly referenced object

Since 0.7.1

### tp_list_connection_managers ()

    void                tp_list_connection_managers         (TpDBusDaemon *bus_daemon,
                                                             TpConnectionManagerListCb callback,
                                                             gpointer user_data,
                                                             GDestroyNotify destroy,
                                                             GObject *weak_object);

List the available (running or installed) connection managers. Call the callback when done.

Since 0.7.26, this function will wait for each TpConnectionManager to be ready, so all connection managers passed to `callback` will be ready (`tp_connection_manager_is_ready()` will return `TRUE`) unless an error occurred while launching that connection manager.

`bus_daemon` : | proxy for the D-Bus daemon
`callback` : | callback to be called when listing the CMs succeeds or fails; not called if the `weak_object` goes away
`user_data` : | user-supplied data for the callback
`destroy` : | callback to destroy the user-supplied data, called after `callback`, but also if the `weak_object` goes away
`weak_object` : | if not `NULL`, will be weakly referenced; the callback will not be called, and the call will be cancelled, if the object has vanished

Since 0.7.1

### TpConnectionManager

    typedef struct {
        TpProxy parent;

        const gchar *name;
        const TpConnectionManagerProtocol * const *protocols;

        /* These are really booleans, but gboolean is signed. Thanks, GLib */
        unsigned int running:1;
        unsigned int always_introspect:1;
        /* TpCMInfoSource, but can't rely on enums being unsigned */
        unsigned int info_source:2;
        guint reserved_flags:28;

        TpConnectionManagerPrivate *priv;
    } TpConnectionManager;

A proxy object for a Telepathy connection manager.

This might represent a connection manager which is currently running (in which case it can be introspected) or not (in which case its capabilities can be read from .manager files in the filesystem). Accordingly, this object never emits "invalidated" unless all references to it are discarded.

Various fields and methods on this object do not work until `tp_connection_manager_is_ready()` returns `TRUE`. Use `tp_connection_manager_call_when_ready()` to wait for this to happen.

TpProxy `parent`; | The parent class instance
const gchar *`name`; | The identifier of the connection manager (e.g. "gabble"). Should be considered read-only
const TpConnectionManagerProtocol * const *`protocols`; | If info_source > `TP_CM_INFO_SOURCE_NONE`, a `NULL`-terminated array of pointers to TpConnectionManagerProtocol structures; otherwise `NULL`. Should be considered read-only
unsigned int `running` :1; | `TRUE` if the CM is currently known to be running. Should be considered read-only
unsigned int `always_introspect` :1; | `TRUE` if the CM will be introspected automatically. Should be considered read-only: use the "always-introspect" property if you want to change it
unsigned int `info_source` :2; | The source of `protocols`, or `TP_CM_INFO_SOURCE_NONE` if no info has been discovered yet
guint `reserved_flags` :28; | Reserved for future use
TpConnectionManagerPrivate *`priv`; | Pointer to opaque private data

Since 0.7.1

### TpConnectionManagerClass

    typedef struct {
    } TpConnectionManagerClass;

The class of a TpConnectionManager.

Since 0.7.1

### tp_connection_manager_new ()

    TpConnectionManager * tp_connection_manager_new         (TpDBusDaemon *dbus,
                                                             const gchar *name,
                                                             const gchar *manager_filename,
                                                             GError **error);

Convenience function to create a new connection manager proxy. If its protocol and parameter information are required, you should call `tp_connection_manager_call_when_ready()` on the result.

`dbus` : | Proxy for the D-Bus daemon
`name` : | The connection manager name (such as "gabble")
`manager_filename` : | The "manager-file" property, which may (and generally should) be `NULL`.
`error` : | used to return an error if `NULL` is returned
Returns : | a new reference to a connection manager proxy, or `NULL` if `error` is set.

### tp_connection_manager_get_name ()

    const gchar *       tp_connection_manager_get_name      (TpConnectionManager *self);

Return the internal name of this connection manager in the Telepathy D-Bus API, e.g. "gabble" or "haze". This is often the name of the binary without the "telepathy-" prefix.

The returned string is valid as long as `self` is. Copy it with `g_strdup()` if a longer lifetime is required.

`self` : | a connection manager
Returns : | the "connection-manager" property

Since 0.7.26

### TpConnectionManagerWhenReadyCb ()

    void                (*TpConnectionManagerWhenReadyCb)   (TpConnectionManager *cm,
                                                             const GError *error,
                                                             gpointer user_data,
                                                             GObject *weak_object);

Called as the result of `tp_connection_manager_call_when_ready()`. If the connection manager's protocol and parameter information could be retrieved, `error` is `NULL` and `cm` is considered to be ready. Otherwise, `error` is non-`NULL` and `cm` is not ready.

`cm` : | a connection manager
`error` : | `NULL` on success, or the reason why `tp_connection_manager_is_ready()` would return `FALSE`
`user_data` : | the `user_data` passed to `tp_connection_manager_call_when_ready()`
`weak_object` : | the `weak_object` passed to `tp_connection_manager_call_when_ready()`

### tp_connection_manager_call_when_ready ()

    void                tp_connection_manager_call_when_ready
                                                            (TpConnectionManager *self,
                                                             TpConnectionManagerWhenReadyCb callback,
                                                             gpointer user_data,
                                                             GDestroyNotify destroy,
                                                             GObject *weak_object);

Call the `callback` from the main loop when information about `cm`'s supported protocols and parameters has been retrieved.

`self` : | a connection manager
`callback` : | callback to call when information has been retrieved or on error
`user_data` : | arbitrary data to pass to the callback
`destroy` : | called to destroy `user_data`
`weak_object` : | object to reference weakly; if it is destroyed, `callback` will not be called, but `destroy` will still be called

Since 0.7.26

### tp_connection_manager_is_ready ()

    gboolean            tp_connection_manager_is_ready      (TpConnectionManager *self);

If protocol and parameter information has been obtained from the connection manager or the cache in the .manager file, return `TRUE`. Otherwise, return `FALSE`.

This may change from `FALSE` to `TRUE` at any time that the main loop is running; the "notify" signal is emitted for the "info-source" property.

`self` : | a connection manager
Returns : | `TRUE`, unless the "info-source" property is `TP_CM_INFO_SOURCE_NONE`

Since 0.7.26

### enum TpCMInfoSource

    typedef enum
    {
      TP_CM_INFO_SOURCE_NONE,
      TP_CM_INFO_SOURCE_FILE,
      TP_CM_INFO_SOURCE_LIVE
    } TpCMInfoSource;

Describes possible sources of information on connection managers' supported protocols.

`TP_CM_INFO_SOURCE_NONE` | no information available
`TP_CM_INFO_SOURCE_FILE` | information came from a .manager file
`TP_CM_INFO_SOURCE_LIVE` | information came from the connection manager

Since 0.7.1

### tp_connection_manager_get_info_source ()

    TpCMInfoSource      tp_connection_manager_get_info_source
                                                            (TpConnectionManager *self);

If protocol and parameter information has been obtained from the connection manager, return `TP_CM_INFO_SOURCE_LIVE`; if it has been obtained from the cache in the .manager file, return `TP_CM_INFO_SOURCE_FILE`. If this information has not yet been obtained, or obtaining it failed, return `TP_CM_INFO_SOURCE_NONE`.

This may increase at any time that the main loop is running; the "notify" signal is emitted.

`self` : | a connection manager
Returns : | the value of the "info-source" property

Since 0.7.26

### tp_connection_manager_activate ()

    gboolean            tp_connection_manager_activate      (TpConnectionManager *self);

Attempt to run and introspect the connection manager, asynchronously. Since 0.7.26 this function is not generally very useful, since the connection manager will now be activated automatically if necessary.

If the CM was already running, do nothing and return `FALSE`.

On success, emit "activated" when the CM appears on the bus, and "got-info" when its capabilities have been (re-)discovered.

On failure, emit "exited" without first emitting activated.

`self` : | a connection manager proxy
Returns : | `TRUE` if activation was needed and is now in progress, `FALSE` if the connection manager was already running and no additional signals will be emitted.

Since 0.7.1

### tp_connection_manager_is_running ()

    gboolean            tp_connection_manager_is_running    (TpConnectionManager *self);

Return `TRUE` if this connection manager currently appears to be running. This may change at any time that the main loop is running; the "activated" and "exited" signals are emitted.

`self` : | a connection manager
Returns : | whether the connection manager is currently running

Since 0.7.26

### tp_connection_manager_dup_protocol_names ()

    gchar **            tp_connection_manager_dup_protocol_names
                                                            (TpConnectionManager *self);

Returns a list of protocol names supported by this connection manager. These are the internal protocol names used by the Telepathy specification (e.g. "jabber" and "msn"), rather than user-visible names in any particular locale.

If this function is called before the connection manager information has been obtained, the result is always `NULL`. Use `tp_connection_manager_call_when_ready()` to wait for this.

The result is copied and must be freed by the caller, but it is not necessarily still true after the main loop is re-entered.

`self` : | a connection manager
Returns : | a GStrv of protocol names

Since 0.7.26

### tp_connection_manager_has_protocol ()

    gboolean            tp_connection_manager_has_protocol  (TpConnectionManager *self,

Return whether `protocol` is supported by this connection manager.

If this function is called before the connection manager information has been obtained, the result is always `FALSE`. Use `tp_connection_manager_call_when_ready()` to wait for this.

`self` : | a connection manager
`protocol` : | the name of a protocol as defined in the Telepathy D-Bus API, e.g. "jabber" or "msn"
Returns : | `TRUE` if this connection manager supports `protocol`

Since 0.7.26

### tp_connection_manager_get_protocol ()

    const TpConnectionManagerProtocol * tp_connection_manager_get_protocol
                                                            (TpConnectionManager *self,
                                                             const gchar *protocol);

Returns a structure representing a protocol, or `NULL` if this connection manager does not support the specified protocol.

If this function is called before the connection manager information has been obtained, the result is always `NULL`. Use `tp_connection_manager_call_when_ready()` to wait for this.

The result is not necessarily valid after the main loop is re-entered.

`self` : | a connection manager
`protocol` : | the name of a protocol as defined in the Telepathy D-Bus API, e.g. "jabber" or "msn"
Returns : | a structure representing the protocol

Since 0.7.26

### TpConnectionManagerProtocol

    typedef struct {
      gchar *name;
      TpConnectionManagerParam *params;
    } TpConnectionManagerProtocol;

Structure representing a protocol supported by a connection manager. Note that the size of this structure may change, so its size must not be relied on.

gchar *`name`; | The name of this connection manager
TpConnectionManagerParam *`params`; | Array of TpConnectionManagerParam structures, terminated by a structure whose `name` is `NULL`

Since 0.7.1

### tp_connection_manager_protocol_can_register ()

                                                            (const TpConnectionManagerProtocol *protocol);

Return whether a new account can be registered on this protocol, by setting the special "register" parameter to `TRUE`.

`protocol` : | structure representing a supported protocol
Returns : | `TRUE` if `protocol` supports the parameter "register"

Since 0.7.26

### tp_connection_manager_protocol_dup_param_names ()

    gchar **            tp_connection_manager_protocol_dup_param_names
                                                            (const TpConnectionManagerProtocol *protocol);

Returns a list of parameter names supported by this connection manager for this protocol.

The result is copied and must be freed by the caller with `g_strfreev()`.

Call the method RequestConnection and run the main loop until it returns. Before calling this method, you must add a reference to any borrowed objects you need to keep, and generally ensure that everything is in a consistent state.

<tp:docstring xmlns="http://www.w3.org/1999/xhtml"> <p>Request a <tp:dbus-ref namespace="org.freedesktop.Telepathy">Connection</tp:dbus-ref> object representing a given account on a given protocol with the given parameters. The method returns the bus name and the object path where the new Connection object can be found, which should have the status of Connection_Status_Disconnected, to allow signal handlers to be attached before connecting is started with the <tp:dbus-ref namespace="org.freedesktop.Telepathy.Connection">Connect</tp:dbus-ref> method.</p> <p>The parameters which must and may be provided in the parameters dictionary can be discovered with the <tp:member-ref>GetParameters</tp:member-ref> method. These parameters, their types, and their default values may be cached in files so that all available connection managers do not need to be started to discover which protocols are available.</p> <p>To request values for these parameters from the user, a client must have prior knowledge of the meaning of the parameter names, so the following well-known names and types should be used where appropriate:</p> <dl> <dt>account (s)</dt> <dd>The identifier for the user's account on the server</dd> <dt>server (s)</dt> <dd>A fully qualified domain name or numeric IPv4 or IPv6 address. Using the fully-qualified domain name form is recommended whenever possible. If this parameter is specified and the account for that protocol also specifies a server, this parameter should override that in the user id.</dd> <dt>port (q)</dt> <dd>A TCP or UDP port number. If this parameter is specified and the account for that protocol also specifies a port, this parameter should override that in the account.</dd> <dt>password (s)</dt> <dd>A password associated with the account.</dd> <dt>require-encryption (b)</dt> <dd>Require encryption for this connection.

The requester can use the returned object path and service name independently of the emission of that signal.

`error` : | If not `NULL`, used to raise an error if `NULL` is returned
Returns : | a TpProxySignalConnection containing all of the above, which can be used to disconnect the signal; or `NULL` if the proxy does not have the desired interface or has become invalid.

## Property Details

### The `"always-introspect"` property

      "always-introspect"        gboolean              : Read / Write

If `TRUE`, always introspect the connection manager as it comes online, even if we already have its info from a .manager file. Default `FALSE`.

Default value: FALSE

### The `"connection-manager"` property

      "connection-manager"       gchar*                : Read

The name of the connection manager, e.g. "gabble" (read-only).

Default value: NULL

### The `"info-source"` property

      "info-source"              guint                 : Read

Where we got the current information on supported protocols (a TpCMInfoSource).

Since 0.7.26, the "notify" signal is emitted for this property.

Allowed values: <= 2

Default value: 0

### The `"manager-file"` property

      "manager-file"             gchar*                : Read / Write / Construct

The absolute path of the .manager file. If set to `NULL` (the default), the XDG data directories will be searched for a .manager file of the correct name.

If set to the empty string, no .manager file will be read.

Default value: NULL

## Signal Details

### The `"activated"` signal

    void                user_function                      (TpConnectionManager *self,
                                                            gpointer             user_data)      : Run Last / Has Details

Emitted when the connection manager's well-known name appears on the bus.

`self` : | the connection manager proxy
`user_data` : | user data set when the signal handler was connected.

### The `"exited"` signal

    void                user_function                      (TpConnectionManager *self,
                                                            gpointer             user_data)      : Run Last / Has Details

Emitted when the connection manager's well-known name disappears from the bus or when activation fails.

`self` : | the connection manager proxy
`user_data` : | user data set when the signal handler was connected.

### The `"got-info"` signal

    void                user_function                      (TpConnectionManager *self,
                                                            guint                source,
                                                            gpointer             user_data)      : Run Last / Has Details

Emitted when the connection manager's capabilities have been discovered.

This signal is not very helpful. Since 0.7.26, using `tp_connection_manager_call_when_ready()` instead is recommended.

`self` : | the connection manager proxy
`source` : | a TpCMInfoSource
`user_data` : | user data set when the signal handler was connected.
