### tp_cli_call_content_media_description_call_accept ()

    TpProxyPendingCall *
    tp_cli_call_content_media_description_call_accept
                                   (gpointer proxy,
                                    gint timeout_ms,
                                    GHashTable *in_Local_Media_Description,
                                    tp_cli_call_content_media_description_callback_for_accept callback,
                                    gpointer user_data,
                                    GDestroyNotify destroy,
                                    GObject *weak_object);

Start a Accept method call.

Accepts the updated Description and update the corresponding local description. If FurtherNegotiationRequired is True, calling this method will generally cause a network round-trip and a new MediaDescription to be offered (hopefully with FurtherNegotiationRequired set to False).

#### Parameters

proxy | the TpProxy |
timeout_ms | the timeout in milliseconds, or -1 to use the default |
in_Local_Media_Description | Used to pass an 'in' argument: The local description to send to the remote contacts and to use in the <tp:dbus-ref namespace="ofdT.Call1">Content</tp:dbus-ref>. |
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.

#### Parameters

                                    GError **error);

Connect a handler to the signal CandidatePairSelected.

Emitted when a candidate is selected for use in the stream by the controlling side of an ICE session. The controlled side should call <tp:member-ref>AcceptSelectedCandidatePair</tp:member-ref> or <tp:member-ref>RejectSelectedCandidatePair</tp:member-ref> when connectivity checks have either succeeded or failed for this candidate pair. See also: <tp:member-ref>SelectedCandidatePairs</tp:member-ref>.

#### Parameters

proxy | A TpProxy 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

a TpProxySignalConnection containing all of the above, which can be used to disconnect the signal; or `NULL` if the proxy does not have the desired interface or has become invalid.
