SD_BUS_LIST_NAMES(3) sd_bus_list_names SD_BUS_LIST_NAMES(3)
sd_bus_list_names - Retrieve information about registered names on a
bus
#include <systemd/sd-bus.h>
int sd_bus_list_names(sd_bus *bus, char ***acquired,
char ***activatable);
sd_bus_list_names() retrieves information about the registered names
on a bus. If acquired is not NULL, this function calls
org.freedesktop.DBus.ListNames[1] to retrieve the list of
currently-owned names on the bus. If acquired is not NULL, the
function calls org.freedesktop.DBus.ListActivableNames[2] to retrieve
the list of all names on the bus that can be activated. Note that
ownership of the arrays returned by sd_bus_list_names() in acquired
and activatable is transferred to the caller and hence, the caller is
responsible for freeing these arrays and their contents.
On success, sd_bus_list_names() returns a non-negative integer. On
failure, it returns a negative errno-style error code.
Errors
Returned errors may indicate the following problems:
-EINVAL
bus or both acquired and activatable were NULL.
-ENOPKG
The bus cannot be resolved.
-ECHILD
The bus was created in a different process.
-ENOMEM
Memory allocation failed.
-ENOTCONN
The bus is not connected.
These APIs are implemented as a shared library, which can be compiled
and linked to with the libsystemd pkg-config(1) file.
