DESCRIPTION

27       sd_bus_slot_get_bus() returns the bus object that message slot is
28       attached to.
29
30       sd_bus_slot_get_current_handler(), sd_bus_slot_get_current_message()
31       and sd_bus_slot_get_current_userdata() return the current handler,
32       message and userdata respectively of the bus slot is attached to if
33       we're currently executing the callback associated with slot.
34

RETURN VALUE

36       sd_bus_slot_get_bus() always returns the bus object.
37
38       On success, sd_bus_slot_get_current_handler(),
39       sd_bus_slot_get_current_message() and
40       sd_bus_slot_get_current_userdata() return the requested object. On
41       failure, they return NULL.
