</para>

<para><function>sd_bus_creds_get_session()</function> will

retrieve the logind session that the process is part of. See

<citerefentry><refentrytitle>systemd-logind.service</refentrytitle><manvolnum>8</manvolnum></citerefentry>. For

processes that are not part of a session returns -ENXIO.

</para>

<para><function>sd_bus_creds_get_owner_uid()</function> will

retrieve the numeric UID (user identifier) of the user who owns

the session that the process is part of. See

<citerefentry><refentrytitle>systemd.slice</refentrytitle><manvolnum>5</manvolnum></citerefentry>

For processes that are not part of a session returns -ENXIO.

</para>

<para><function>sd_bus_creds_has_effective_cap()</function> will

check whether the capability specified by

<parameter>capability</parameter> was set in the effective

capabilities mask. A positive return value means that is was

set, zero means that it was not set, and a negative return

value signifies an error. See

<citerefentry project='man-pages'><refentrytitle>capabilities</refentrytitle><manvolnum>7</manvolnum></citerefentry>

and <varname>Capabilities=</varname> and

<varname>CapabilityBoundingSet=</varname> settings in

<citerefentry><refentrytitle>systemd.exec</refentrytitle><manvolnum>5</manvolnum></citerefentry>.

</para>

<para><function>sd_bus_creds_has_permitted_cap()</function> is

similar to <function>sd_bus_creds_has_effective_cap()</function>,

but will check the permitted capabilities mask.</para>

<para><function>sd_bus_creds_has_inheritable_cap()</function> is

similar to <function>sd_bus_creds_has_effective_cap()</function>,

but will check the inheritable capabilities mask.</para>

<para><function>sd_bus_creds_get_audit_login_uid()</function> will

retrieve the audit user login identifier (the identifier of the

user who is "responsible" for the session). Returns -ENXIO for

processes that are not part of an audit session.</para>

<para><function>sd_bus_creds_get_tty()</function> will retrieve

the controlling TTY. Returns -ENXIO for processes that have no

controlling TTY.</para>

<para><function>sd_bus_creds_get_unique_name()</function> will

D-Bus specification</ulink>.</para>

<para><function>sd_bus_creds_get_description()</function> will

peer. This name is useful to discern multiple bus connections by

the same peer, and may be altered by the peer with the

<citerefentry><refentrytitle>sd_bus_set_description</refentrytitle><manvolnum>3</manvolnum></citerefentry>

call.</para>

<para>All functions that take a <parameter>const

char**</parameter> parameter will store the answer there as an

address of a NUL-terminated string. It will be valid as long as

<parameter>c</parameter> remains valid, and should not be freed or

modified by the caller.</para>

<para>All functions that take a <parameter>char***</parameter>

parameter will store the answer there as an address of a an array

of strings. Each individual string is NUL-terminated, and the

array is NULL-terminated as a whole. It will be valid as long as

<parameter>c</parameter> remains valid, and should not be freed or

modified by the caller.</para>
