                                GObject *weak_object);

Start a AcceptFile method call.

Accept a file transfer that's in the Pending state. The file transfer's state becomes Accepted after this method is called. At this point the client can connect to the socket. CM MUST emit <tp:member-ref>InitialOffsetDefined</tp:member-ref> and change the state to Open before writing to the socket. Then <tp:member-ref>InitialOffset</tp:member-ref> should be respected in case its value differs from the offset that was specified as an argument to AcceptFile.

Parameters

proxy	the TpProxy
timeout_ms	the timeout in milliseconds, or -1 to use the default
in_Address_Type	Used to pass an 'in' argument: The type of address the connection manager should listen on. (TpSocketAddressType)
in_Access_Control	Used to pass an 'in' argument: The type of access control the connection manager should apply to the socket. (TpSocketAccessControl)
in_Access_Control_Param	Used to pass an 'in' argument: A parameter for the access control type, to be interpreted as specified in the documentation for the Socket_Access_Control enum.
in_Offset	Used to pass an 'in' argument: The desired offset in bytes where the file transfer should start. The offset is taken from the beginning of the file. Specifying an offset of zero will start the transfer from the beginning of the file. The offset that is actually given in the <tp:member-ref>InitialOffset</tp:member-ref> property can differ from this argument where the requested offset is not supported. (For example, some protocols do not support offsets at all so the InitialOffset property will always be 0.)
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.

                                GObject *weak_object);

Start a ProvideFile method call.

Provide the file for an outgoing file transfer which has been offered. Opens a socket that the client can use to provide a file to the connection manager. The channel MUST have been requested, and will change state to Open when this method is called if its state was Accepted.

in_Access_Control_Param	Used to pass an 'in' argument: A parameter for the access control type, to be interpreted as specified in the documentation for the Socket_Access_Control enum.
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

proxy	A TpChannel 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`

Parameters

proxy	A TpChannel 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`

tp_cli_channel_type_file_transfer_connect_to_transferred_bytes_changed
                               (TpChannel *proxy,
                                tp_cli_channel_type_file_transfer_signal_callback_transferred_bytes_changed callback,
                                gpointer user_data,

                                GError **error);

Connect a handler to the signal TransferredBytesChanged.

Emitted when the number of transferred bytes changes. This will not be signalled with every single byte change. Instead, the most frequent this signal will be emitted is once a second. This should be sufficient, and the <tp:member-ref>TransferredBytes</tp:member-ref> property SHOULD NOT be polled.

Parameters

proxy	A TpChannel 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`

                                GError **error);

Connect a handler to the signal URIDefined.

Emitted when the value of the <tp:member-ref>URI</tp:member-ref> property has been set. This signal MUST only be emitted on incoming file transfers, and only if the handler sets the <tp:member-ref>URI</tp:member-ref> property before accepting the file.

Parameters

proxy	A TpChannel or subclass
callback	Callback to be called when the signal is received
user_data	User-supplied data for the callback

Parameters

proxy	A TpChannel or subclass
timeout_ms	Timeout in milliseconds, or -1 for default
in_Address_Type	Used to pass an 'in' argument: The type of address the connection manager should listen on. (TpSocketAddressType)
in_Access_Control	Used to pass an 'in' argument: The type of access control the connection manager should apply to the socket. (TpSocketAccessControl)
in_Access_Control_Param	Used to pass an 'in' argument: A parameter for the access control type, to be interpreted as specified in the documentation for the Socket_Access_Control enum.
in_Offset	Used to pass an 'in' argument: The desired offset in bytes where the file transfer should start. The offset is taken from the beginning of the file. Specifying an offset of zero will start the transfer from the beginning of the file. The offset that is actually given in the <tp:member-ref>InitialOffset</tp:member-ref> property can differ from this argument where the requested offset is not supported. (For example, some protocols do not support offsets at all so the InitialOffset property will always be 0.)
out_Address	Used to return an 'out' argument if `TRUE` is returned: The address on which the connection manager will listen for connections for this file transfer.
error	If not `NULL`, used to return errors if `FALSE` is returned
loop	If not `NULL`, set before re-entering the main loop, to point to a GMainLoop which can be used to cancel this call with `g_main_loop_quit()`, causing a return of `FALSE` with `error` set to `TP_DBUS_ERROR_CANCELLED`

Returns

TRUE on success, FALSE and sets error on error
