<para><function>sd_bus_send()</function> queues the bus message object <parameter>m</parameter>
|
||||
for transfer. If <parameter>bus</parameter> is <constant>NULL</constant>, the bus that
|
||||
<parameter>m</parameter> is attached to is used. <parameter>bus</parameter> only needs to be set
|
||||
when the message is sent to a different bus than the one it's attached to, for example when
|
||||
forwarding messages. If the output parameter <parameter>cookie</parameter> is not
|
||||
<constant>NULL</constant>, it is set to the message identifier. This value can later be used to
|
||||
match incoming replies to their corresponding messages. If <parameter>cookie</parameter> is set
|
||||
to <constant>NULL</constant> and the message is not sealed, <function>sd_bus_send()</function>
|
||||
assumes the message <parameter>m</parameter> doesn't expect a reply and adds the necessary
|
||||
headers to indicate this.</para>
|
||||
|

<para>Note that in most scenarios, <function>sd_bus_send()</function> should not be called
