.SH DESCRIPTION
+.SS baudrate
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.
-
+.SS erasechar, erasewchar
+.PP
The \fBerasechar\fR routine returns the user's current erase character.
-
+.PP
+The \fBerasewchar\fR routine stores the current erase character
+in the location referenced by \fIch\fR.
+If no erase character has been defined, the routine fails
+and the location referenced by \fIch\fR is not changed.
+.SS has_is, has_il
+.PP
The \fBhas_ic\fR routine is true if the terminal has insert- and delete-
character capabilities.
-
+.PP
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.
-
+.SS killchar, killwchar
+.PP
The \fBkillchar\fR routine returns the user's current line kill character.
-
+.PP
+The \fBkillwchar\fR routine stores the current line-kill character
+in the location referenced by \fIch\fR.
+If no line-kill character has been defined,
+the routine fails and the location referenced by \fIch\fR is not changed.
+.SS longname
+.PP
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
\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.

+.SS termattrs, term_attrs
+.PP
+If a given terminal does not 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 \fBOR\fR of all video attributes supported by the
-terminal. This information is useful when a \fBcurses\fR program
+different video attribute for it.
+The \fBtermattrs\fR and \fBterm_attrs\fR functions
+return a logical \fBOR\fR of all video attributes supported by the
+terminal using \fIA_\fR and \fIWA_\fR constants respectively.
+This information is useful when a \fBcurses\fR program
needs complete control over the appearance of the screen.
-
-The \fBtermname\fR routine returns the value of the environmental
-variable \fBTERM\fR (truncated to 14 characters).
+.SS termname
+.PP
+The \fBtermname\fR routine returns the terminal name used by \fBsetupterm\fR.
.SH RETURN VALUE
\fBlongname\fR and \fBtermname\fR return \fBNULL\fR on error.
-
+.PP
Routines that return an integer return \fBERR\fR upon failure and \fBOK\fR
(SVr4 only specifies "an integer value other than \fBERR\fR") upon successful
completion.
.SH PORTABILITY
The XSI Curses standard, Issue 4 describes these functions. It changes the
return type of \fBtermattrs\fR to the new type \fBattr_t\fR.
+Most versions of curses truncate the result returned by \fBtermname\fR to
+14 characters.
