NAME
       sd_get_seats, sd_get_sessions, sd_get_uids, sd_get_machine_names -
       Determine available seats, sessions, logged in users and virtual
       machines/containers

SYNOPSIS
       #include <systemd/sd-login.h>

       int sd_get_seats(char*** seats);

       int sd_get_sessions(char*** sessions);

       int sd_get_uids(uid_t** users);

       int sd_get_machine_names(char*** machines);

DESCRIPTION
       sd_get_seats() may be used to determine all currently available local
       seats. Returns a NULL terminated array of seat identifiers. The
       returned array and all strings it references need to be freed with the
       libc free(3) call after use. Note that instead of an empty array NULL
       may be returned and should be considered equivalent to an empty array.

       Similarly, sd_get_sessions() may be used to determine all current login
       sessions.

       Similarly, sd_get_uids() may be used to determine all Unix users who
       currently have login sessions.

       Similarly, sd_get_machine_names() may be used to determine all current
       virtual machines and containers on the system.

       Note that the returned lists are not sorted and in an undefined order.

RETURN VALUE
       On success, sd_get_seats(), sd_get_sessions(), sd_get_uids() and
       sd_get_machine_names() return the number of entries in the arrays. On
       failure, these calls return a negative errno-style error code.

NOTES
       The sd_get_seats(), sd_get_sessions(), sd_get_uids() and
       sd_get_machine_names() interfaces are available as a shared library,
       which can be compiled and linked to with the libsystemd-login pkg-
       config(1) file.
