File transfer — client-side wrappers for the File Transfer channel type

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.

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.

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.

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.

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.

Warning

tp_cli_channel_type_file_transfer_run_accept_file is deprecated and should not be used in newly-written code.

Call the method AcceptFile and run the main loop until it returns. Before calling this method, you must add a reference to any borrowed objects you need to keep, and generally ensure that everything is in a consistent state.

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.

proxy :

timeout_ms :

Used to pass an 'in' argument: The type of address the connection manager should listen on. (TpSocketAddressType)

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
