Headers                                            utmpx.h(3HEAD)



NAME
     utmpx.h, utmpx - user accounting database definitions

SYNOPSIS
     #include 


DESCRIPTION
     The  header  defines  the  utmpx  structure,  which
     includes the following members:

       char                  ut_user[];  /* user login name */
       char                  ut_id[];    /* unspecified initialization */
                                         /* process identifier */
       char                  ut_line[];  /* device name */
       pid_t                 ut_pid;     /* process ID */
       short                 ut_type;    /* type of entry */



     for X/Open compilation environments:

       struct ut_exit_status ut_exit; /* process termination/exit status*/



     for all other compilation environments:

       struct exit_status    ut_exit;    /* process termination/exit status*/


       struct timeval        ut_tv;      /* time entry was made */
       int                   ut_session; /* session ID, used for windowing */
       short                 ut_syslen;  /* significant length of ut_host */
                                         /* including terminating null */
       char                  ut_host[];  /* remote host name */



     The pid_t type is defined through typedef  as  described  in
     .


     The  timeval  structure   is   defined   as   described   in
     .


     Inclusion of the  header can also make visible  all
     symbols from .

Headers                                            utmpx.h(3HEAD)



     The following symbolic constants  are  defined  as  possible
     values for the ut_type member of the utmpx structure:

     EMPTY            No valid user accounting information.


     BOOT_TIME        Identifies time of system boot.


     OLD_TIME         Identifies time when system clock changed.


     NEW_TIME         Identifies time after system clock changed.


     USER_PROCESS     Identifies a process.


     INIT_PROCESS     Identifies a process spawned  by  the  init
                      process.


     LOGIN_PROCESS    Identifies the session leader of a  logged-
                      in user.


     DEAD_PROCESS     Identifies a session leader who has exited.
