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
m[blue]org.freedesktop.DBus.ListNamesm[][1]
to retrieve the list of currently-owned names on the bus. If
acquired
is not
NULL, the function calls
m[blue]org.freedesktop.DBus.ListActivableNamesm[][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.
-ENOMEM
-
Memory allocation failed.
-ENOTCONN
-
The bus is not connected.
NOTES
These APIs are implemented as a shared library, which can be compiled and linked to with the
libsystemd pkg-config(1)
file.
