DESCRIPTION
sd_bus_slot_get_bus() returns the bus object that message slot is attached to. sd_bus_slot_get_current_handler(), sd_bus_slot_get_current_message() and sd_bus_slot_get_current_userdata() return the current handler, message and userdata respectively of the bus slot is attached to if we're currently executing the callback associated with slot.RETURN VALUE
sd_bus_slot_get_bus() always returns the bus object. On success, sd_bus_slot_get_current_handler(), sd_bus_slot_get_current_message() and sd_bus_slot_get_current_userdata() return the requested object. On failure, they return NULL.NOTES
These APIs are implemented as a shared library, which can be compiled and linked to with the libsystemd pkg-config(1) file.SEE ALSO
