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 to retrieve the list of currently-owned names on the bus. If
acquired
is not NULL
, the function calls
org.freedesktop.DBus.ListActivableNames 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.
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.
