<para>Whenever sd-bus is about to invoke a user-supplied callback function, it stores the
current callback, D-Bus message, slot and userdata pointer and allows these to be queried via
- these <function>sd_bus_get_current_handler()</function>,
+ <function>sd_bus_get_current_handler()</function>,
<function>sd_bus_get_current_message()</function>,
<function>sd_bus_get_current_slot()</function> and
<function>sd_bus_get_current_userdata()</function>, respectively. If <parameter>bus</parameter>
cannot be resolved or if execution does not reside in a user-supplied callback of
- <parameter>bus</parameter> when calling any of these functions, they return
- <constant>NULL</constant>.</para>
+ <parameter>bus</parameter>, these functions return <constant>NULL</constant>.</para>
