<para><function>sd_event_source_set_io_fd()</function> changes the UNIX file descriptor of an I/O event
source created previously with <function>sd_event_add_io()</function>. It takes the event source object
and the new file descriptor. If the event source takes the ownership of the previous file descriptor,
that is, <function>sd_event_source_set_io_fd_own()</function> was called for the event source with a
and the new file descriptor as parameters. If the event source owned the previous file descriptor, that
is if <function>sd_event_source_set_io_fd_own()</function> had been called for the event source with a
non-zero value, then the previous file descriptor will be closed and the event source will also take the
ownership of the new file descriptor on success.</para>
<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 (or when the file descriptor
assigned to the event source is replaced by <function>sd_event_source_set_io_fd()</function>), 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>
event source shall take ownership of the file descriptor. Takes a boolean parameter
<parameter>b</parameter>. When true (nonzero), the file descriptor will be closed automatically when the
event source is freed or when the file descriptor is replaced by
<function>sd_event_source_set_io_fd()</function>. By default the descriptor is not owned by the event
source, and the application has to do close it on its own if needed.</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
