## Includes

    #include <telepathy-glib/telepathy-glib-dbus.h>

## Description

Many Telepathy Channel objects can be seen as representing groups or sets of contacts. The Telepathy specification represents this by a common interface, Group. This section documents the auto-generated C wrappers for the Group interface.

Contacts can be in four states:

- in the group (the "members" set)

- "local pending" (waiting to be added to the group by the local client calling `AddMembers()`)

- "remote pending" (waiting to be added to the group by some other action, probably by someone else)

- no relationship with the group at all

For instance, chatrooms implement the Group interface. Contacts in the chatroom are members, and contacts who we've invited to the group, or contacts who've requested permission to join, are remote pending. If the local user has been invited by another contact, they will appear in the local-pending set until they accept or decline the invitation.

Some Group channels also have the Conference interface, representing a group which can be initiated by upgrading or merging one or more 1-1 channels.

## Functions

### tp_cli_channel_interface_group_run_add_members ()

    gboolean
    tp_cli_channel_interface_group_run_add_members
                                   (TpChannel *proxy,
                                    gint timeout_ms,
                                    const GArray *in_Contacts,
                                    const gchar *in_Message,
                                    GError **error,
                                    GMainLoop **loop);

`tp_cli_channel_interface_group_run_add_members` is deprecated and should not be used in newly-written code.

Call the method AddMembers 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>Invite all the given contacts into the channel, or accept requests for channel membership for contacts on the pending local list.</p> <p>A message may be provided along with the request, which will be sent to the server if supported. See the CHANNEL_GROUP_FLAG_MESSAGE_ADD and CHANNEL_GROUP_FLAG_MESSAGE_ACCEPT <tp:member-ref>GroupFlags</tp:member-ref> to see in which cases this message should be provided.</p> <p>Attempting to add contacts who are already members is allowed; connection managers must silently accept this, without error.</p>

#### Parameters

proxy | A TpChannel or subclass |
timeout_ms | Timeout in milliseconds, or -1 for default |
in_Contacts | Used to pass an 'in' argument: An array of contact handles to invite to the channel |
in_Message | Used to pass an 'in' argument: A string message, which can be blank if desired |
error | If not `NULL`, used to return errors if `FALSE` is returned |
loop | If not `NULL`, set before re-entering the main loop, to point to a GMainLoop which can be used to cancel this call with `g_main_loop_quit()`, causing a return of `FALSE` with `error` set to `TP_DBUS_ERROR_CANCELLED` |

#### Returns

TRUE on success, FALSE and sets `error` on error

### tp_cli_channel_interface_group_run_get_all_members ()

    gboolean
    tp_cli_channel_interface_group_run_get_all_members
                                   (TpChannel *proxy,
                                    gint timeout_ms,

                                    GMainLoop **loop);

`tp_cli_channel_interface_group_run_get_all_members` is deprecated and should not be used in newly-written code.

Use GetAll on the D-Bus Properties D-Bus interface to get properties including Members, RemotePendingMembers and LocalPendingMembers instead, falling back to this method and GetLocalPendingMembersWithInfo if necessary.

Call the method GetAllMembers 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.

Returns arrays of all current, local and remote pending channel members.

#### Parameters

proxy | A TpChannel or subclass |

error | If not `NULL`, used to return errors if `FALSE` is returned |
loop | If not `NULL`, set before re-entering the main loop, to point to a GMainLoop which can be used to cancel this call with `g_main_loop_quit()`, causing a return of `FALSE` with `error` set to `TP_DBUS_ERROR_CANCELLED` |

#### Returns

TRUE on success, FALSE and sets `error` on error

                                    GMainLoop **loop);

`tp_cli_channel_interface_group_run_get_group_flags` is deprecated and should not be used in newly-written code.

Use GetAll on the D-Bus Properties D-Bus interface to get properties including GroupFlags instead, falling back to this method if necessary.

Call the method GetGroupFlags 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.

Returns the value of the <tp:member-ref>GroupFlags</tp:member-ref> property.

#### Parameters

                                    GMainLoop **loop);

`tp_cli_channel_interface_group_run_get_handle_owners` is deprecated and should not be used in newly-written code.

Clients should use the HandleOwners property and HandleOwnersChanged signal if Channel_Group_Flag_Properties is present.

Call the method GetHandleOwners 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.

If the CHANNEL_GROUP_FLAG_CHANNEL_SPECIFIC_HANDLES flag is set on the channel, then the handles of the group members are specific to this channel, and are not meaningful in a connection-wide context such as contact lists. This method allows you to find the owner of the handle if it can be discovered in this channel, or 0 if the owner is not available.

#### Parameters

proxy | A TpChannel or subclass |
timeout_ms | Timeout in milliseconds, or -1 for default |
in_Handles | Used to pass an 'in' argument: A list of integer handles representing members of the channel |

error | If not `NULL`, used to return errors if `FALSE` is returned |
loop | If not `NULL`, set before re-entering the main loop, to point to a GMainLoop which can be used to cancel this call with `g_main_loop_quit()`, causing a return of `FALSE` with `error` set to `TP_DBUS_ERROR_CANCELLED` |

#### Returns

TRUE on success, FALSE and sets `error` on error
