<title>Description</title>
|
|
|
|
<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>
