+
+ <para><function>sd_event_source_set_io_fd_own()</function> controls whether the file descriptor of the event source
+ shall be closed automatically when the event source is freed, i.e. whether it shall be considered 'owned' by the
+ event source object. By default it is not closed automatically, and the application has to do this on its own. The
+ <parameter>b</parameter> parameter is a boolean parameter: if zero, the file descriptor is not closed automatically
+ when the event source is freed, otherwise it is closed.</para>
+
+ <para><function>sd_event_source_get_io_fd_own()</function> may be used to query the current setting of the file
+ descriptor ownership boolean flag as set with <function>sd_event_source_set_io_fd_own()</function>. It returns
+ positive if the file descriptor is closed automatically when the event source is destroyed, zero if not, and
+ negative on error.</para>
