|
|
|
|
<para><function>sd_event_source_get_event()</function> may be used
|
|
to retrieve the event loop object the event source object specified
|
|
as <parameter>source</parameter> is associated with. The event
|
|
loop object is specified when creating an event source object with
|
|
calls such as
|
|
<citerefentry><refentrytitle>sd_event_add_io</refentrytitle><manvolnum>3</manvolnum></citerefentry>
|
|
or
|
|
<citerefentry><refentrytitle>sd_event_add_time</refentrytitle><manvolnum>3</manvolnum></citerefentry>.</para>
