## Description

`sd_bus_get_name_creds()` queries the credentials of the bus client identified by name. The mask parameter is a combo of `SD_BUS_CREDS_*` flags that indicate which credential info the caller is interested in. See sd_bus_creds_new_from_pid 3 for a list of possible flags. On success, creds contains a new sd_bus_creds instance with the requested information. Ownership of this instance belongs to the caller and it should be freed once no longer needed by calling sd_bus_creds_unref 3.

`sd_bus_get_owner_creds()` queries the credentials of the creator of the given bus. The mask and creds parameters behave the same as in `sd_bus_get_name_creds()`.

## Return Value

On success, these functions return a non-negative integer. On failure, they return a negative errno-style error code.

### Errors

Returned errors may indicate the following problems:

`-EINVAL`

  An argument is invalid.

`-ENOPKG`

  The bus cannot be resolved.

`-EPERM`

  The bus has already been started.

`-ECHILD`

  The bus was created in a different process.

`-ENOMEM`

  Memory allocation failed.
