16 sd_bus_list_names() retrieves information about the registered names on
17 a bus. If acquired is not NULL, this function calls
18 org.freedesktop.DBus.ListNames[1] to retrieve the list of
19 currently-owned names on the bus. If acquired is not NULL, the function
20 calls org.freedesktop.DBus.ListActivableNames[2] to retrieve the list
21 of all names on the bus that can be activated. Note that ownership of
22 the arrays returned by sd_bus_list_names() in acquired and activatable
23 is transferred to the caller and hence, the caller is responsible for
24 freeing these arrays and their contents.
25
27 On success, sd_bus_list_names() returns a non-negative integer. On
28 failure, it returns a negative errno-style error code.

30 Errors
31 Returned errors may indicate the following problems:
32
33 -EINVAL
34 bus or both acquired and activatable were NULL.
35
36 -ENOPKG
37 The bus cannot be resolved.
38
39 -ECHILD

41
42 -ENOMEM
43 Memory allocation failed.
44
45 -ENOTCONN

49 These APIs are implemented as a shared library, which can be compiled
50 and linked to with the libsystemd pkg-config(1) file.
