## Description

TpCallContent is a sub-class of TpProxy providing convenient API to represent TpCallChannel's content.

## Functions

### tp_call_content_init_known_interfaces ()

    void
    tp_call_content_init_known_interfaces (void);

Ensure that the known interfaces for TpCallContent 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_CALL_CONTENT`.

    TpCallContentDisposition
    tp_call_content_get_disposition (TpCallContent *self);

### tp_call_content_remove_async ()

    void

                                  gpointer user_data);

Remove the content from the call. This will cause “removed” to be emitted.

#### Parameters

self | a TpCallContent |
callback | a callback to call when the operation finishes |
user_data | data to pass to `callback` |

Since 0.17.5

### tp_call_content_remove_finish ()

                                      gpointer user_data);

Send `tones` DTMF code on `self` content. `self` must have the `TP_IFACE_CALL_CONTENT_INTERFACE_DTMF` interface.

If DTMF tones are already being played, this request is queued.

#### Parameters

self | a TpCallContent |
tones | a string representation of one or more DTMF events. |
cancellable | optional GCancellable object, `NULL` to ignore |
callback | a callback to call when the operation finishes |
user_data | data to pass to `callback` |

    gboolean
    tp_call_content_send_tones_finish (TpCallContent *self,
                                       GAsyncResult *result,
                                       GError **error);

Finishes `tp_call_content_send_tones_async()`.

#### Parameters

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

#### Returns

## Types and Values

### TpCallContent

    typedef struct _TpCallContent TpCallContent;

Data structure representing a TpCallContent.

Since 0.17.5
