SD_BUS_LIST_NAMES(3) sd_bus_list_names SD_BUS_LIST_NAMES(3)

NAME
sd_bus_list_names - Retrieve information about registered names on a
bus

SYNOPSIS
#include <systemd/sd-bus.h>

int sd_bus_list_names(sd_bus *bus, char ***acquired,
char ***activatable);

DESCRIPTION
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.

RETURN VALUE
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, library or module
instance.

-ENOMEM
Memory allocation failed.

-ENOTCONN
The bus is not connected.

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.
