                                gpointer user_data);

Provide a file transfer. This should be called when the file transfer state changes (tp_file_transfer_channel_get_state() and the "notify::state" signal) to TP_FILE_TRANSFER_STATE_ACCEPTED or TP_FILE_TRANSFER_STATE_PENDING. Once the file has been provided, the channel “state” will change to TP_FILE_TRANSFER_STATE_OPEN.

Once the file has been provided, callback will be called. You should then call tp_file_transfer_channel_provide_file_finish() to get the result of the operation.

Since: 0.17.1

tp_file_transfer_channel_provide_file_finish ()

gboolean

                                GError **error);

Finishes a call to tp_file_transfer_channel_provide_file_async().

Successful return from this function does not mean that the file transfer has completed or has even started at all. The state of the file transfer should be monitored with the "notify::state" signal.

struct TpFileTransferChannel

struct TpFileTransferChannel;

Data structure representing a TpFileTransferChannel.

TP_FILE_TRANSFER_CHANNEL_FEATURE_CORE

#define             TP_FILE_TRANSFER_CHANNEL_FEATURE_CORE

Expands to a call to a function that returns a quark for the "core" feature on a TpFileTransferChannel.

When this feature is prepared, the “transferred-bytes” property has been retrieved and will be updated.

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

Since: 0.15.5

The “date” property

  “date”                     GDateTime *

A GDateTime representing the last modification time of the file to be transferred.

Since 0.15.5

Owner: TpFileTransferChannel

The “description” property

  “description”              gchar *

The description of the file transfer, defined by the sender when sending the file transfer offer.

Since 0.15.5

Owner: TpFileTransferChannel

Flags: Read

Default value: NULL

The “file” property

  “file”                     GFile *

For incoming file transfers, this property will be set to a GFile for the location where the file will be saved (given by tp_file_transfer_channel_accept_file_async()) when the transfer starts. The feature TP_FILE_TRANSFER_CHANNEL_FEATURE_CORE must already be prepared for this property to have a meaningful value, and to receive change notification. Once the initial value is set, this property will not be changed.

For outgoing file transfers, this property is a GFile for the location of the file being sent (given by tp_file_transfer_channel_provide_file_async()). The feature TP_FILE_TRANSFER_CHANNEL_FEATURE_CORE does not have to be prepared and there is no change notification.

Owner: TpFileTransferChannel

Flags: Read

Since: 0.17.1

The “filename” property

  “filename”                 gchar *

The name of the file on the sender's side. This is therefore given as a suggested filename for the receiver.

Since 0.15.5

Owner: TpFileTransferChannel

Flags: Read

Default value: NULL

The “initial-offset” property

  “initial-offset”           guint64

The offset in bytes from where the file should be sent.

The TP_FILE_TRANSFER_CHANNEL_FEATURE_CORE feature has to be prepared for this property to be meaningful and kept up to date.

Owner: TpFileTransferChannel

Flags: Read

Default value: 0

Since: 0.17.1

The “metadata” property

  “metadata”                 GHashTable_gchararray+GStrv_*

Additional information about the file transfer set by the channel initiator, or an empty GHashTable if the initiator did not provide any additional information.

To provide metadata along with a file offer, include TP_PROP_CHANNEL_INTERFACE_FILE_TRANSFER_METADATA_METADATA in the channel request. For example:

1
2
3
4
5

7
8

The “mime-type” property

  “mime-type”                gchar *

The MIME type of the file to be transferred.

Owner: TpFileTransferChannel

Flags: Read

Default value: NULL

Since: 0.15.5

The “service-name” property

  “service-name”             gchar *

A string representing the name of the service suggested to handle this file transfer channel, or NULL if the initiator did not provide one.

This is a useful way of requesting file transfer channels with a hint of what handler they should be handled by on the remote side. If a channel request is made with this property set (to a contact who also supports the metadata extension; see the requestable channel classes for said contact), this property will be set to the same value on the remote incoming channel and handlers can match on this in their handler filter. For example, a remote handler could call the following:

1
2
3
4
5
6

tp_base_client_take_handler_filter (handler, tp_asv_new (
              TP_PROP_CHANNEL_CHANNEL_TYPE, G_TYPE_STRING, TP_IFACE_CHANNEL_TYPE_FILE_TRANSFER,
              TP_PROP_CHANNEL_TARGET_HANDLE_TYPE, G_TYPE_UINT, TP_HANDLE_TYPE_CONTACT,
              TP_PROP_CHANNEL_REQUESTED, G_TYPE_BOOLEAN, FALSE,
              TP_PROP_CHANNEL_INTERFACE_FILE_TRANSFER_METADATA_SERVICE_NAME, G_TYPE_STRING, "service.name",
              NULL));
