NAME
       utmpx.h, utmpx - user accounting database definitions

SYNOPSIS
       #include <utmpx.h>

DESCRIPTION
       The <utmpx.h> 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 <sys/types.h>.

       The timeval structure is defined as described in <sys/time.h>.

       Inclusion of the <utmpx.h> header can also make visible all symbols from <sys/time.h>.

       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.
