<title>Description</title>
|
|
|
|
<para><function>sd_bus_get_name_creds()</function> queries the credentials of the bus client
|
|
identified by <parameter>name</parameter>. The <parameter>mask</parameter> parameter is a combo of
|
|
<constant index='false'>SD_BUS_CREDS_*</constant> flags that indicate which credential info the caller is
|
|
interested in. See
|
|
<citerefentry><refentrytitle>sd_bus_creds_new_from_pid</refentrytitle><manvolnum>3</manvolnum></citerefentry>
|
|
for a list of possible flags. On success, <parameter>creds</parameter> contains a new
|
|
<structname>sd_bus_creds</structname> instance with the requested information. Ownership of this instance
|
|
belongs to the caller and it should be freed once no longer needed by calling
|
|
<citerefentry><refentrytitle>sd_bus_creds_unref</refentrytitle><manvolnum>3</manvolnum></citerefentry>.
|
|
</para>
|
|
|
|
<para><function>sd_bus_get_owner_creds()</function> queries the credentials of the creator of the given
|
|
bus. The <parameter>mask</parameter> and <parameter>creds</parameter> parameters behave the same as in
|
|
<function>sd_bus_get_name_creds()</function>.</para>
