+    <title>Description</title>
+
+    <para><function>sd_get_seats()</function> may be used to determine
+    all currently available local seats. Returns the number of seat
+    identifiers and if the input pointer is non-<constant>NULL</constant>, a
+    <constant>NULL</constant>-terminated array of seat identifiers
+    is stored at the address.
+    The returned array and all strings it references need to be freed
+    with the libc
+    <citerefentry project='man-pages'><refentrytitle>free</refentrytitle><manvolnum>3</manvolnum></citerefentry>
+    call after use. Note that instead of an empty array
+    <constant>NULL</constant> may be returned and should be considered
+    equivalent to an empty array.</para>
+
+    <para>Similarly, <function>sd_get_sessions()</function> may be
+    used to determine all current login sessions.</para>
+
+    <para>Similarly, <function>sd_get_uids()</function> may be used to
+    determine all Unix users who currently have login sessions.</para>
+
+    <para>Similarly, <function>sd_get_machine_names()</function> may
+    be used to determine all current virtual machines and containers
+    on the system.</para>
+
+    <para>Note that the returned lists are not sorted and in an
+    undefined order.</para>
+  </refsect1>
+

+    <title>Return Value</title>
+
+    <para>On success, <function>sd_get_seats()</function>, <function>sd_get_sessions()</function>,
+    <function>sd_get_uids()</function> and <function>sd_get_machine_names()</function> return the number of
+    entries in the arrays. On failure, these calls return a negative errno-style error code.</para>
+
+    <refsect2>
+      <title>Errors</title>
+
+      <para>Returned errors may indicate the following problems:</para>
