- <para><function>sd_seat_get_sessions()</function> may be used to
- determine all sessions on the specified seat. Returns two arrays,
- one (<constant>NULL</constant> terminated) with the session
- identifiers of the sessions and one with the user identifiers of
- the Unix users the sessions belong to. An additional parameter may
- be used to return the number of entries in the latter array. This
- value is the same the return value, if the latter is nonnegative.
- The two arrays and the last parameter may be passed as
- <constant>NULL</constant> in case these values need not to be
- determined. The arrays and the strings referenced by them 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>
