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

Functions described here are available as a shared library, which can be compiled against and linked to with the libsystemd pkg-config (1) file.

The code described here uses getenv (3), which is declared to be not multi-thread-safe. This means that the code calling the functions described here must not call setenv (3) from a parallel thread. It is recommended to only do calls to setenv() from an early phase of the program when no other threads have been started.

HISTORY
