## Includes

## 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`.

Since: 0.17.5

### tp_call_content_get_disposition ()

    TpCallContentDisposition
    tp_call_content_get_disposition (TpCallContent *self);

Since: 0.17.5

### tp_call_content_remove_async ()

    void

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. |

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

                                       GAsyncResult *result,
                                       GError **error);

Finishes `tp_call_content_send_tones_async()`.

#### Parameters

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

#### Returns

`TRUE` on success, `FALSE` otherwise.

## Types and Values

### TpCallContent

    typedef struct _TpCallContent TpCallContent;

Data structure representing a TpCallContent.

Since: 0.17.5

### struct TpCallContentClass

    struct TpCallContentClass {
    };

The class of a TpCallContent.

### TP_CALL_CONTENT_FEATURE_CORE

    #define             TP_CALL_CONTENT_FEATURE_CORE

One can ask for a feature to be prepared using the `tp_proxy_prepare_async()` function, and waiting for it to trigger the callback.
