<title>Description</title>
<para><function>sd_bus_close()</function> disconnects the specified bus connection. When this call is invoked and
the specified bus object refers to an active connection it is immediately terminated. No further messages may be
sent or received on it. Any messages queued in the bus object (both incoming and outgoing) are released. If
invoked on <constant>NULL</constant> bus object or when the bus connection is already closed this function executes
no operation. This call does not free or unreference the bus object itself. Use
<citerefentry><refentrytitle>sd_bus_unref</refentrytitle><manvolnum>3</manvolnum></citerefentry> for that.</para>

<para>Before a program exits it is usually a good idea to flush any pending messages with
<function>sd_bus_flush()</function> and then close connections with <function>sd_bus_close()</function> to ensure
that no unwritten messages are lost, no further messages may be queued and all incoming but unprocessed messages
are released. After both operations have been done, it is a good idea to also drop any remaining references to the
bus object so that it may be freed. Since these three operations are frequently done together a helper call
<citerefentry><refentrytitle>sd_bus_flush_close_unref</refentrytitle><manvolnum>3</manvolnum></citerefentry> is
provided that combines them into one.</para>
