17
19 sd_bus_get_name_creds() queries the credentials of the bus client
20 identified by name. The mask parameter is a combo of SD_BUS_CREDS_*
21 flags that indicate which credential info the caller is interested in.
22 See sd_bus_creds_new_from_pid(3) for a list of possible flags. On
23 success, creds contains a new sd_bus_creds instance with the requested
24 information. Ownership of this instance belongs to the caller and it
25 should be freed once no longer needed by calling sd_bus_creds_unref(3).
26
27 sd_bus_get_owner_creds() queries the credentials of the creator of the
28 given bus. The mask and creds parameters behave the same as in
29 sd_bus_get_name_creds().
30
32 On success, these functions return a non-negative integer. On failure,
33 they return a negative errno-style error code.
34
35 Errors
36 Returned errors may indicate the following problems:
37
38 -EINVAL
39 An argument is invalid.
40
41 -ENOPKG
42 The bus cannot be resolved.
43
44 -EPERM
45 The bus has already been started.
46
47 -ECHILD
48 The bus was created in a different process.
49
50 -ENOMEM
51 Memory allocation failed.
52
54 These APIs are implemented as a shared library, which can be compiled
55 and linked to with the libsystemd pkg-config(1) file.
