NAME
sd_get_seats, sd_get_sessions, sd_get_uids - Determine available seats, sessions and logged in users
SYNOPSIS
#include <systemd/sd-login.h> int sd_get_seats(char*** seats); int sd_get_sessions(char*** sessions); int sd_get_uids(char*** sessions);
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. Similar, sd_get_sessions() may be used to determine all current login sessions. Similar, sd_get_uids() may be used to determine all Unix users who currently have login sessions.
RETURN VALUE
On success sd_get_seats(), sd_get_sessions() and sd_get_uids() 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() and sd_get_uids() interfaces are available as shared library, which can be compiled and linked to with the libsystemd-login pkg-config(1) file.
