Fields

ut_type: c_short

Type of record

ut_pid: pid_t

PID of login process

ut_line: [u8; 32]

Device name of tty - "/dev/"

ut_id: [u8; 4]

Terminal name suffix, or inittab(5) ID

ut_user: [u8; 32]

Username

ut_host: [u8; 256]

Hostname for remote login, or kernel version for run-level message

ut_exit: exit_status

Exit status of a process marked as DEAD_PROCESS; not used by Linux init

ut_session: i32

Session ID (getsid(2)) used for windowing

ut_tv: timeval
