The following states are currently - known: <literal>offline</literal> (user not logged in - at all), <literal>lingering</literal> (user not logged - in, but some user services running), - <literal>online</literal> (user logged in, but not - active, i.e. has no session in the foreground), - <literal>active</literal> (user logged in, and has at - least one active session, i.e. one session in the - foreground), <literal>closing</literal> (user not - logged in, and not lingering, but some processes are - still around). In the future additional states might - be defined, client code should be written to be robust - in regards to additional state strings being - returned. The returned string needs to be freed with - the libc - <citerefentry><refentrytitle>free</refentrytitle><manvolnum>3</manvolnum></citerefentry> - call after use.</para> - - <para><function>sd_uid_is_on_seat()</function> may be - used to determine whether a specific user is logged in - or active on a specific seat. Accepts a Unix user - identifier and a seat identifier string as - parameters. The <parameter>require_active</parameter> - parameter is a boolean value. If non-zero (true) this - function will test if the user is active (i.e. has a - session that is in the foreground and accepting user - input) on the specified seat, otherwise (false) only - if the user is logged in (and possibly inactive) on - the specified seat.</para> - - <para><function>sd_uid_get_sessions()</function> may - be used to determine the current sessions of the - specified user. Accepts a Unix user identifier as - parameter. The <parameter>require_active</parameter> - parameter controls whether the returned list shall - consist of only those sessions where the user is - currently active (> 0), where the user is currently - online but possibly inactive (= 0), or - logged in at all but possibly closing the session (< 0). The call returns a - NULL terminated string array of session identifiers in - <parameter>sessions</parameter> which needs to be - freed by the caller with the libc - <citerefentry><refentrytitle>free</refentrytitle><manvolnum>3</manvolnum></citerefentry> - call after use, including all the strings - referenced. If the string array parameter is passed as - NULL the array will not be filled in, but the return - code still indicates the number of current - sessions. Note that instead of an empty array NULL may - be returned and should be considered equivalent to an - empty array.</para> - - <para>Similar, <function>sd_uid_get_seats()</function> - may be used to determine the list of seats on which - the user currently has sessions. Similar semantics - apply, however note that the user may have - multiple sessions on the same seat as well as sessions - with no attached seat and hence the number of entries - in the returned array may differ from the one returned - by <function>sd_uid_get_sessions()</function>.</para> - </refsect1> - - <refsect1> - <title>Return Value</title> - - <para>On success - <function>sd_uid_get_state()</function> returns 0 or a - positive integer.
