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

79 | <title>Return Value</title> | |
80 | ||
81 | <para>On success, <function>sd_event_source_get_event()</function> | |
82 | returns the associated event loop object. On failure, it returns | |
