.SH NAME
htmp \- home directory and teletype data base
.SH DESCRIPTION
The home directory and teletype data base
.I htmp
is used to partially simulate version 7 environments, by
.I setenv (UCB),
and the
.I getenv
subroutine of
.IR libretro (UCB).
The file consists of an array of structures of the form:
.PP
.DT
	\fBstruct\fR htmp {
.br
		\fBshort\fR	uid;
.br
		\fBchar\fR	home[28];
.br
		\fBshort\fR	ttytype;
.br
	};
.PP
The
.it ttytype
is actually a two character code, and is defined by
.IR termcap (UCB).
.PP
The file is indexed by the various teletypes in a system dependent fashion,
using the result of a call to ttyn (3).
.PP
A set of routines internal to
.IR libretro (UCB)
allows easy access to this data base.
