                                    gint timeout_ms,
                                    guint in_Contact,
                                    gboolean in_Receive,

                                    GObject *weak_object);

Start a RequestReceiving method call.

<p>Request that a remote contact stops or starts sending on this stream.</p> <p>The <tp:member-ref>CanRequestReceiving</tp:member-ref> property defines whether the protocol allows the local user to request the other side start sending on this stream.</p>

#### Parameters

proxy | the TpProxy |
timeout_ms | the timeout in milliseconds, or -1 to use the default |
in_Contact | Used to pass an 'in' argument: <tp:docstring xmlns="http://www.w3.org/1999/xhtml"> <p>Contact from which sending is requested</p> (TpContactHandle) |
in_Receive | Used to pass an 'in' argument: <tp:docstring xmlns="http://www.w3.org/1999/xhtml"> <p>If true, request that the given contact starts to send media. If false, request that the given contact stops sending media.</p> |
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.

This indicates to the CM that the initial batch of candidates has been added, and should now be processed/sent to the remote side. <tp:rationale> Protocols supporting Raw UDP SHOULD wait for FinishInitialCandidates, and then set the lowest priority candidate as the Raw UDP candidate. </tp:rationale>

#### Parameters

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 |

destroy | called with the user_data as argument, after the call has succeeded, failed or been cancelled; must be `NULL` if `callback` is `NULL` |

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` |

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.
