## Description

TpDBusTubeChannel provides API for working with D-Bus tube channels, which allow applications to open D-Bus connections to a contact or chat room.

To create a new outgoing D-Bus tube channel, do something like:

## Functions

### tp_dbus_tube_channel_get_parameters ()

    GHashTable *
    tp_dbus_tube_channel_get_parameters (TpDBusTubeChannel *self);

Return the “parameters” property

[skip]

#### Parameters

self | a TpDBusTubeChannel |

#### Returns

the value of “parameters”.

[transfer none][element-type utf8 GObject.Value]

Since: 0.18.0

### tp_dbus_tube_channel_dup_parameters_vardict ()

    GVariant *
    tp_dbus_tube_channel_dup_parameters_vardict
                                   (TpDBusTubeChannel *self);

Return the parameters of the dbus-tube channel in a variant of type `G_VARIANT_TYPE_VARDICT` whose keys are strings representing parameter names and values are variants representing corresponding parameter values set by the offerer when offering this channel.

The GVariant returned is `NULL` if this is an outgoing tube that has not yet been offered or the parameters property has not been set.

Use `g_variant_lookup()`, `g_variant_lookup_value()`, or `tp_vardict_get_uint32()` and similar functions for convenient access to the values.

#### Parameters

self | a TpDBusTubeChannel |

#### Returns

a new reference to a GVariant.

### tp_dbus_tube_channel_get_service_name ()

    const gchar *
    tp_dbus_tube_channel_get_service_name (TpDBusTubeChannel *self);

Return the “service-name” property

#### Parameters

self | a TpDBusTubeChannel |

#### Returns

the value of “service-name”.

[transfer none]

Since: 0.18.0

### tp_dbus_tube_channel_offer_async ()

    void
    tp_dbus_tube_channel_offer_async (TpDBusTubeChannel *self,
                                      GHashTable *params,
                                      GAsyncReadyCallback callback,
                                      gpointer user_data);

Offer an outgoing D-Bus tube. When the tube has been offered and accepted `callback` will be called. You can then call `tp_dbus_tube_channel_offer_finish()` to get the GDBusConnection that will be used to communicate through the tube.

#### Parameters

self | an outgoing TpDBusTubeChannel |
params | parameters of the tube, or `NULL`. | [allow-none][transfer none]
callback | a callback to call when the tube has been offered |
user_data | data to pass to `callback` |

Since: 0.18.0

### tp_dbus_tube_channel_offer_finish ()

    GDBusConnection *
    tp_dbus_tube_channel_offer_finish (TpDBusTubeChannel *self,
                                       GAsyncResult *result,
                                       GError **error);

Finishes offering an outgoing D-Bus tube. The returned GDBusConnection is ready to be used to exchange data through the tube.

#### Parameters

self | a TpDBusTubeChannel |
result | a GAsyncResult |
error | a GError to fill |

#### Returns

a reference on a GDBusConnection if the tube has been successfully offered and opened; `NULL` otherwise.

### tp_dbus_tube_channel_accept_async ()

    void
    tp_dbus_tube_channel_accept_async (TpDBusTubeChannel *self,
                                       GAsyncReadyCallback callback,
                                       gpointer user_data);

Accept an incoming D-Bus tube. When the tube has been accepted `callback` will be called. You can then call `tp_dbus_tube_channel_accept_finish()` to get the GDBusConnection that will be used to communicate through the tube.

#### Parameters

self | an incoming TpDBusTubeChannel |
callback | a callback to call when the tube has been offered |
user_data | data to pass to `callback` |

Since: 0.18.0

### tp_dbus_tube_channel_accept_finish ()

                                        GError **error);

Finishes to accept an incoming D-Bus tube. The returned GDBusConnection is ready to be used to exchange data through the tube.

#### Parameters

self | a TpDBusTubeChannel |
result | a GAsyncResult |
error | a GError to fill |

#### Returns

a reference on a GDBusConnection if the tube has been successfully accepted and opened; `NULL` otherwise.

## Property Details

### The `“parameters”` property

      “parameters”               GHashTable_gchararray+GValue_*

A string to GValue GHashTable representing the parameters of the tube.

Will be `NULL` for outgoing tubes until the tube has been offered.

In high-level language bindings, use `tp_dbus_tube_channel_dup_parameters_vardict()` to get the same information in a more convenient format.

Owner: TpDBusTubeChannel

Flags: Read

Since: 0.18.0

### The `“parameters-vardict”` property

      “parameters-vardict”       GVariant *

A `G_VARIANT_TYPE_VARDICT` representing the parameters of the tube.

Will be `NULL` for outgoing tubes until the tube has been offered.

Owner: TpDBusTubeChannel

Flags: Read

Allowed values: GVariant<a{sv}>

Default value: NULL

Since: 0.19.10

### The `“service-name”` property

      “service-name”             char *

A string representing the service name that will be used over the tube.

Owner: TpDBusTubeChannel

Flags: Read

Default value: NULL

Since: 0.18.0
