+
+ <para><filename>sd-login.h</filename> provides APIs to
+ introspect and monitor seat, login session and user
+ status information on the local system. </para>
+
+ <para>See <ulink
+ url="http://www.freedesktop.org/wiki/Software/systemd/multiseat">Multi-Seat
+ on Linux</ulink> for an introduction into multi-seat
+ support on Linux, the background for this set of APIs.</para>
+
+ <para>Note that these APIs only allow purely passive access
+ and monitoring of seats, sessions and users. To
+ actively make changes to the seat configuration,
+ terminate login sessions, or switch session on a seat
+ you need to utilize the D-Bus API of
+ systemd-logind.</para>

<para><function>sd_pid_get_session()</function> may be
used to determine the login session identifier of a
- process identified by the specified process identifier. The session
- identifier is a short string (up to 64 characters),
- consisting only of the characters a-zA-Z0-9 as well as
- '-' and '_'. It is suitable for usage in file system
- paths. Note that not all processes are part of a login
- session (e.g. system service processes and user
- processes that are shared between multiple sessions of
- the same user). For processes not being part of a
- login session this function will fail. The returned
- string needs to be freed with the libc
+ process identified by the specified process
+ identifier. The session identifier is a short string,
+ suitable for usage in file system paths. Note that not
+ all processes are part of a login session (e.g. system
+ service processes and user processes that are shared
