Returns an array of seat identifiers. The returned array and all strings it references need to be freed with the libc free3 call after use. 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. 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. 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-config1 file. systemd1, sd-login7, sd_session_get_seat3,
