.SH DESCRIPTION
.sp
.LP
The \fBbaudrate()\fR routine returns the output speed of the terminal. The
number returned is in bits per second, for example \fB9600\fR, and is an
integer.
.sp
.LP
With the \fBerasechar()\fR routine, the user's current erase character is
returned.
.sp
.LP
The \fBhas_ic()\fR routine is true if the terminal has insert- and
delete-character capabilities.
.sp
.LP
The \fBhas_il()\fR routine is true if the terminal has insert- and delete-line
capabilities, or can simulate them using scrolling regions. This might be used
to determine if it would be appropriate to turn on physical scrolling using
\fBscrollok()\fR.
.sp
.LP
With the \fBkillchar()\fR routine, the user's current line kill character is
returned.
.sp
.LP
The \fBlongname()\fR routine returns a pointer to a static area containing a
verbose description of the current terminal. The maximum length of a verbose
description is 128 characters. It is defined only after the call to
\fBinitscr()\fR or \fBnewterm()\fR. The area is overwritten by each call to
\fBnewterm()\fR and is not restored by \fBset_term()\fR, so the value should be
saved between calls to \fBnewterm()\fR if \fBlongname()\fR is going to be used
with multiple terminals.
.sp
.LP
If a given terminal doesn't support a video attribute that an application
program is trying to use, \fBcurses\fR may substitute a different video
attribute for it. The \fBtermattrs()\fR function returns a logical OR of all
video attributes supported by the terminal. This information is useful when a
\fBcurses\fR program needs complete control over the appearance of the screen.
.sp
.LP
The \fBtermname()\fR routine returns the value of the environment variable
\fBTERM\fR (truncated to 14 characters).
.SH RETURN VALUES
.sp
.LP
\fBlongname()\fR and \fBtermname()\fR return \fINULL\fR on error.
.sp
.LP
Routines that return an integer return \fBERR\fR upon failure and an integer
value other than \fBERR\fR upon successful completion.
