.SH SYNOPSIS
.LP
.nf
#include <utmpx.h>
.fi
.SH DESCRIPTION
.sp
.LP
The \fB<utmpx.h>\fR header defines the \fButmpx\fR structure, which includes
the following members:
.sp
.in +2
.nf
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 */
.fi
.in -2
.sp
.LP
for X/Open compilation environments:
.sp
.in +2
.nf
struct ut_exit_status ut_exit; /* process termination/exit status*/
.fi
.in -2
.sp
.LP
for all other compilation environments:
.sp
.in +2
.nf
struct exit_status ut_exit; /* process termination/exit status*/
.fi
.in -2
.sp
.in +2
.nf
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 */
.fi
.in -2
.sp
.LP
The \fBpid_t\fR type is defined through \fBtypedef\fR as described in
\fB<sys/types.h>\fR.
.sp
.LP
The \fBtimeval\fR structure is defined as described in \fB<sys/time.h>\fR.
.sp
.LP
Inclusion of the \fB<utmpx.h>\fR header can also make visible all symbols from
\fB<sys/time.h>\fR.
.sp
.LP
The following symbolic constants are defined as possible values for the
\fBut_type\fR member of the \fButmpx\fR structure:
.sp
