NAME

       sd_bus_slot_get_bus, sd_bus_slot_get_current_handler, sd_bus_slot_get_current_message,
       sd_bus_slot_get_current_userdata - Query information attached to a bus slot object

SYNOPSIS

       #include <systemd/sd-bus.h>

       typedef int (*sd_bus_message_handler_t)(sd_bus_message *m, void *userdata,
                                               sd_bus_error *ret_error);

       sd_bus *sd_bus_slot_get_bus(sd_bus_slot *slot);

       sd_bus_message_handler_t sd_bus_slot_get_current_handler(sd_bus_slot *slot);

       sd_bus_message *sd_bus_slot_get_current_message(sd_bus_slot *slot);

       void *sd_bus_slot_get_current_userdata(sd_bus_slot *slot);

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.
