## Includes

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

## Description

A major use for instant messaging is obviously to send messages. Channels of type Text represent IM conversations or chat rooms.

This section documents the auto-generated C wrappers for the Text channel type, and also for the Chat State and Password interfaces, which are usually used in conjunction with Text channels.

## Functions

### tp_cli_channel_type_text_run_acknowledge_pending_messages ()

    gboolean
    tp_cli_channel_type_text_run_acknowledge_pending_messages
                                   (TpChannel *proxy,
                                    gint timeout_ms,
                                    const GArray *in_IDs,
                                    GError **error,
                                    GMainLoop **loop);

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

Call the method AcknowledgePendingMessages 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.

Inform the channel that you have handled messages by displaying them to the user (or equivalent), so they can be removed from the pending queue.

#### Parameters

proxy | A TpChannel or subclass |
timeout_ms | Timeout in milliseconds, or -1 for default |
in_IDs | Used to pass an 'in' argument: The IDs of the messages to acknowledge |
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_type_text_run_get_message_types ()

    gboolean

                                    GArray **out_Available_Types,
                                    GError **error,
                                    GMainLoop **loop);

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

Consulting MessageTypes is preferred.

Call the method GetMessageTypes 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.

Return an array indicating which types of message may be sent on this channel.

#### Parameters

proxy | A TpChannel or subclass |
timeout_ms | Timeout in milliseconds, or -1 for default |
out_Available_Types | Used to return an 'out' argument if `TRUE` is returned: An array of integer message types (ChannelTextMessageType) |
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_type_text_run_list_pending_messages` is deprecated and should not be used in newly-written code.

Consulting PendingMessages is preferred.

Call the method ListPendingMessages 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.

List the messages currently in the pending queue, and optionally remove then all.

#### Parameters

proxy | A TpChannel or subclass |
timeout_ms | Timeout in milliseconds, or -1 for default |
in_Clear | Used to pass an 'in' argument: If true, behave as if <tp:member-ref>AcknowledgePendingMessages</tp:member-ref> had also been called. |
out_Pending_Messages | Used to return an 'out' argument if `TRUE` is returned: <tp:docstring xmlns="http://www.w3.org/1999/xhtml"> An array of structs representing the pending queue. Each contains: <ul> <li>a numeric identifier</li> <li>a Unix timestamp indicating when the message was received</li> <li>the contact handle for the contact who sent the message</li> <li>the message type, taken from ChannelTextMessageType</li> <li>the bitwise-OR of the message flags from ChannelTextMessageFlags</li> <li>the text of the message</li> </ul> |
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

#### Parameters

proxy | A TpChannel or subclass |
callback | Callback to be called when the signal is received |
user_data | User-supplied data for the callback |
destroy | Destructor for the user-supplied data, which will be called when this signal is disconnected, or before this function returns `NULL` |
weak_object | A GObject which will be weakly referenced; if it is destroyed, this callback will automatically be disconnected |
error | If not `NULL`, used to raise an error if `NULL` is returned |

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

This method has never been implemented, and in any case would have been impossible to use correctly when multiple clients (such as a logger and the handler) are interested in a text channel. See freedesktop.org bug 26417 for more details.

Start a GetPendingMessageContent method call.

Retrieve the content of one or more parts of a pending message. Note that this function may take a considerable amount of time to return if the part's 'needs-retrieval' flag is true; consider extending the default D-Bus method call timeout. Additional API is likely to be added in future, to stream large message parts.

#### Parameters

proxy | the TpProxy |
timeout_ms | the timeout in milliseconds, or -1 to use the default |
in_Message_ID | Used to pass an 'in' argument: The ID of a pending message (TpMessageID) |
in_Parts | Used to pass an 'in' argument: The desired entries in the array of message parts, identified by their position. The &quot;headers&quot; part (which is not a valid argument to this method) is considered to be part 0, so the valid part numbers start at 1 (for the second Message_Part). |
callback | called when the method call succeeds or fails; may be `NULL` to make a "fire and forget" call with no reply tracking |
user_data | user-supplied data passed to the callback; must be `NULL` if `callback` is `NULL` |
destroy | called with the user_data as argument, after the call has succeeded, failed or been cancelled; must be `NULL` if `callback` is `NULL` |
weak_object | If not `NULL`, a GObject which will be weakly referenced; if it is destroyed, this call will automatically be cancelled. Must be `NULL` if `callback` is `NULL` |

#### Returns

a TpProxyPendingCall representing the call in progress. It is borrowed from the object, and will become invalid when the callback is called, the call is cancelled or the TpProxy becomes invalid.

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

This method has never been implemented, and in any case would have been impossible to use correctly when multiple clients (such as a logger and the handler) are interested in a text channel. See freedesktop.org bug 26417 for more details.

Call the method GetPendingMessageContent 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.

Retrieve the content of one or more parts of a pending message. Note that this function may take a considerable amount of time to return if the part's 'needs-retrieval' flag is true; consider extending the default D-Bus method call timeout. Additional API is likely to be added in future, to stream large message parts.

#### Parameters

proxy | A TpChannel or subclass |
timeout_ms | Timeout in milliseconds, or -1 for default |
in_Message_ID | Used to pass an 'in' argument: The ID of a pending message (TpMessageID) |
in_Parts | Used to pass an 'in' argument: The desired entries in the array of message parts, identified by their position. The &quot;headers&quot; part (which is not a valid argument to this method) is considered to be part 0, so the valid part numbers start at 1 (for the second Message_Part). |
out_Content | Used to return an 'out' argument if `TRUE` is returned: <tp:docstring xmlns="http://www.w3.org/1999/xhtml"> <p>The content of the requested parts. The keys in this mapping are positions in the array of message parts; the values are either of type 's' or 'ay' (UTF-8 text string, or byte array), following the same rules as for the value of the 'content' key in the <tp:type>Message_Part</tp:type> mappings.</p> <p>If the one of the requested part numbers was greater than zero but referred to a part that had no content (i.e. it had no 'content-type' key or no 'content' key), it is simply omitted from this mapping; this is not considered to be an error condition.</p> |
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

Connect a handler to the signal MessageReceived.

Signals that a message has been received and added to the pending messages queue. This MUST be emitted exactly once per emission of the <tp:dbus-ref namespace="org.freedesktop.Telepathy.Channel.Type.Text">Received</tp:dbus-ref> signal on the Text interface, for backwards-compatibility; clients SHOULD ignore the latter in favour of this signal if this interface is present, as mentioned in the introduction.

#### Parameters

proxy | A TpChannel or subclass |
callback | Callback to be called when the signal is received |
user_data | User-supplied data for the callback |
destroy | Destructor for the user-supplied data, which will be called when this signal is disconnected, or before this function returns `NULL` |
weak_object | A GObject which will be weakly referenced; if it is destroyed, this callback will automatically be disconnected |
error | If not `NULL`, used to raise an error if `NULL` is returned |

#### Returns

If the channel has channel-specific handles, the <code>message-sender</code> and <code>message-sender-id</code> SHOULD reflect the sender that other contacts will see.</p> <p>If the connection manager can predict that the message will be altered during transmission, this argument SHOULD reflect what other contacts will receive, rather than being a copy of the argument to SendMessage (if the message is truncated, formatting or alternatives are dropped, etc., then the edited version SHOULD appear in this signal).</p> |
arg_Flags | <p>Flags affecting how the message was sent. The flags might be a subset of those passed to SendMessage if the caller requested unsupported flags.</p> (TpMessageSendingFlags) |
arg_Message_Token | An opaque token used to match any incoming delivery or failure reports against this message, or an empty string if the message is not readily identifiable. |

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

Call the method ProvidePassword 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.

Provide the password so that the channel can be joined. Must be called with the correct password in order for channel joining to proceed if the 'provide' password flag is set.

#### Parameters

proxy | A TpChannel or subclass |
timeout_ms | Timeout in milliseconds, or -1 for default |
in_Password | Used to pass an 'in' argument: The password |
out_Correct | Used to return an 'out' argument if `TRUE` is returned: A boolean indicating whether or not the password was correct |
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

Start a GetPasswordFlags method call.

Returns the bitwise-OR of the flags relevant to the password on this channel. The user interface can use this to present information about which operations are currently valid.

#### Parameters

proxy | the TpProxy |
timeout_ms | the timeout in milliseconds, or -1 to use the default |
callback | called when the method call succeeds or fails; may be `NULL` to make a "fire and forget" call with no reply tracking |
user_data | user-supplied data passed to the callback; must be `NULL` if `callback` is `NULL` |
destroy | called with the user_data as argument, after the call has succeeded, failed or been cancelled; must be `NULL` if `callback` is `NULL` |
