Type definition for a function that will be called back when an asynchronous operation within GIO has been completed. AsyncReadyCallback callbacks from Task are guaranteed to be invoked in a later iteration of the [thread-default main context][g-main-context-push-thread-default] where the Task was created. All other users of AsyncReadyCallback must likewise call it asynchronously in a later iteration of the main context.

The asynchronous operation is guaranteed to have held a reference to sourceObject from the time when the *_async() function was called, until after this callback returns.

Signature for function used in dBusConnectionAddFilter.

A filter function is passed a DBusMessage and expected to return a DBusMessage too. Passive filter functions that don't modify the message can simply return the message object: > >static GDBusMessage * >passive_filter (GDBusConnection *connection > GDBusMessage *message, > gboolean incoming, > gpointer user_data) >{ > // inspect @message > return message; >}

Filter functions that wants to drop a message can simply return Nothing: > >static GDBusMessage * >drop_filter (GDBusConnection *connection > GDBusMessage *message, > gboolean incoming, > gpointer user_data) >{ > if (should_drop_message) > { > g_object_unref (message); > message = NULL; > } > return message; >}

Finally, a filter function may modify a message by copying it: > >static GDBusMessage * >modifying_filter (GDBusConnection *connection > GDBusMessage *message, > gboolean incoming, > gpointer user_data) >{ > GDBusMessage *copy; > GError *error; > > error = NULL; > copy = g_dbus_message_copy (message, &error); > // handle error being set > g_object_unref (message); > > // modify copy > > return copy; >}

If the returned DBusMessage is different from message and cannot be sent on connection (it could use features, such as file descriptors, not compatible with connection), then a warning is logged to standard error. Applications can check this ahead of time using dBusMessageToBlob passing a DBusCapabilityFlags value obtained from connection.

The type of the introspect function in DBusSubtreeVTable.

Subtrees are flat. node, if non-Nothing, is always exactly one segment of the object path (ie: it never contains a slash).

This function should return Nothing to indicate that there is no object at this node.

If this function returns non-Nothing, the return value is expected to be a Nothing-terminated array of pointers to DBusInterfaceInfo structures describing the interfaces implemented by node. This array will have dBusInterfaceInfoUnref called on each item before being freed with free.

The difference between returning Nothing and an array containing zero items is that the standard DBus interfaces will returned to the remote introspector in the empty array case, but not in the Nothing case.

This callback type is used by g_file_measure_disk_usage() to make periodic progress reports when measuring the amount of disk spaced used by a directory.

These calls are made on a best-effort basis and not all types of File will support them. At the minimum, however, one call will always be made immediately.

In the case that there is no support, reporting will be set to False (and the other values undefined) and no further calls will be made. Otherwise, the reporting will be True and the other values all-zeros during the first (immediate) call. In this way, you can know which type of progress UI to show without a delay.

For g_file_measure_disk_usage() the callback is made directly. For g_file_measure_disk_usage_async() the callback is made via the default main context of the calling thread (ie: the same way that the final async result would be reported).

currentSize is in the same units as requested by the operation (see FileMeasureFlagsApparentSize).

The frequency of the updates is implementation defined, but is ideally about once every 200ms.

The last progress callback may or may not be equal to the final result. Always check the async result to get the final value.
