<title>Description</title>
|
|
||||||
|
|
||||||
<para><function>sd_bus_add_node_enumerator()</function> adds a D-Bus node enumerator for the
|
|
||||||
given path prefix. The given callback is called to enumerate all the available objects with
|
|
||||||
the given path prefix when required (e.g. when
|
|
||||||
<constant>org.freedesktop.DBus.Introspectable.Introspect</constant> or
|
|
||||||
<constant>org.freedesktop.DBus.ObjectManager.GetManagedObjects</constant> are called on a
|
|
||||||
D-Bus service managed by sd-bus).</para>
|
|
||||||
|
|
||||||
<para><parameter>callback</parameter> is called with the path and userdata pointer registered
|
|
||||||
with <function>sd_bus_add_node_enumerator()</function>. When called, it should store all the
|
|
||||||
child object paths of the given path prefix in <parameter>ret_nodes</parameter> and return the
|
|
||||||
number of child objects under the given prefix. If an error occurs, it can either return a
|
|
||||||
negative integer, set <parameter>ret_error</parameter> to a non-empty error or do both. Any
|
|
||||||
errors returned by the callback are encoded as D-Bus errors and sent back to the caller. Errors
|
|
||||||
in <parameter>ret_error</parameter> take priority over negative return values.</para>
|
|
||||||
|
|
||||||
<para>Note that a node enumerator callback will only ever be called for a single path prefix
|
|
||||||
and hence, for normal operation, <parameter>prefix</parameter> can be ignored. Also, a node
|
|
||||||
enumerator is only used to enumerate the available child objects under a given prefix. To
|
|
||||||
install a handler for a set of dynamic child objects, use
|
|
||||||
<citerefentry><refentrytitle>sd_bus_add_fallback_vtable</refentrytitle><manvolnum>3</manvolnum></citerefentry>.
|
|
||||||
</para>
|
|
||||||
|
|
||||||
<para>When <function>sd_bus_add_node_enumerator()</function> succeeds, a slot is created
|
|
||||||
internally. If the output parameter <replaceable>slot</replaceable> is <constant>NULL</constant>,
|
|
||||||
a "floating" slot object is created, see
|
|
||||||
<citerefentry><refentrytitle>sd_bus_slot_set_floating</refentrytitle><manvolnum>3</manvolnum></citerefentry>.
|
|
||||||
Otherwise, a pointer to the slot object is returned. In that case, the reference to the slot
|
|
||||||
object should be dropped when the node enumerator is not needed anymore, see
|
|
||||||
<citerefentry><refentrytitle>sd_bus_slot_unref</refentrytitle><manvolnum>3</manvolnum></citerefentry>.

<title>Description</title>
|
|
||||||
|
|
||||||
<para><function>sd_bus_emit_signal()</function> is a convenience function for initializing a
|
|
||||||
bus message object and emitting the corresponding D-Bus signal. It combines the
|
|
||||||
<citerefentry><refentrytitle>sd_bus_message_new_signal</refentrytitle><manvolnum>3</manvolnum></citerefentry>,
|
|
||||||
<citerefentry><refentrytitle>sd_bus_message_append</refentrytitle><manvolnum>3</manvolnum></citerefentry> and
|
|
||||||
<citerefentry><refentrytitle>sd_bus_send</refentrytitle><manvolnum>3</manvolnum></citerefentry>
|
|
||||||
functions into a single function call. <function>sd_bus_emit_signalv()</function> is
|
|
||||||
equivalent to <function>sd_bus_message_append()</function>, except that it is called with a
|
|
||||||
<literal>va_list</literal> instead of a variable number of arguments.</para>
|
|
||||||
|
|
||||||
<para><function>sd_bus_emit_interfaces_added()</function> and
|
|
||||||
<function>sd_bus_emit_interfaces_removed()</function> are used to implement the
|
|
||||||
<function>InterfacesAdded</function> and <function>InterfacesRemoved</function> signals of the
|
|
||||||
<constant>org.freedesktop.DBus.ObjectManager</constant> interface. They take a path whose
|
|
||||||
interfaces have been modified as an argument and a variable list of interfaces that have been
|
|
||||||
added or removed, respectively. The final argument passed to
|
|
||||||
<function>sd_bus_emit_interfaces_added()</function> and
|
|
||||||
<function>sd_bus_emit_interfaces_removed()</function> <emphasis>must</emphasis> be
|
|
||||||
<constant>NULL</constant>. This allows both functions to safely determine the number of passed
|
|
||||||
interface arguments. <function>sd_bus_emit_interfaces_added_strv()</function> and
|
|
||||||
<function>sd_bus_emit_interfaces_removed_strv()</function> are identical to their respective
|
|
||||||
counterparts but both take the list of interfaces as a single argument instead of a variable
|
|
||||||
number of arguments.</para>
|
|
||||||
|
|
||||||
<para><function>sd_bus_emit_properties_changed()</function> is used to implement the
|
|
||||||
<function>PropertiesChanged</function> signal of the
|
|
||||||
<constant>org.freedesktop.DBus.Properties</constant> interface. It takes an object path,
|
|
||||||
interface and a variable list of property names as its arguments. The final argument passed to
|
|
||||||
<function>sd_bus_emit_properties_changed()</function> <emphasis>must</emphasis> be
|
|
||||||
<constant>NULL</constant>. This allows it to safely determine the number of passed property
|
|
||||||
names. <function>sd_bus_emit_properties_changed_strv()</function> is identical to
|
|
||||||
<function>sd_bus_emit_properties_changed()</function> but takes the list of property names as a
|
|
||||||
single argument instead of a variable number of arguments.</para>
|
|
||||||
|
|
||||||
<para><function>sd_bus_emit_object_added()</function> and
|
|
||||||
<function>sd_bus_emit_object_removed()</function> are convenience functions for emitting the
|
|
||||||
<function>InterfacesAdded</function> or <function>InterfacesRemoved</function> signals for all
|
|
||||||
interfaces registered on a specific object path, respectively. This includes any parent fallback
|
|
||||||
vtables if they are not overridden by a more applicable child vtable. It also includes all the
|
|
||||||
standard D-Bus interfaces implemented by sd-bus itself on any registered object.</para>

|
|
||||||
<para>Whenever sd-bus is about to invoke a user-supplied callback function, it stores the
|
|
||||||
current callback, D-Bus message, slot and userdata pointer and allows these to be queried via
|
|
||||||
these <function>sd_bus_get_current_handler()</function>,
|
|
||||||
<function>sd_bus_get_current_message()</function>,
|
|
||||||
<function>sd_bus_get_current_slot()</function> and
|
|
||||||
<function>sd_bus_get_current_userdata()</function>, respectively. If <parameter>bus</parameter>
|
|
||||||
cannot be resolved or if execution does not reside in a user-supplied callback of
|
|
||||||
<parameter>bus</parameter> when calling any of these functions, they return
|
|
||||||
<constant>NULL</constant>.</para>
