<H2>DESCRIPTION</H2><PRE>
The <STRONG>baudrate</STRONG> routine returns the output speed of the ter-
minal. The number returned is in bits per second, for
example <STRONG>9600</STRONG>, and is an integer.
The <STRONG>erasechar</STRONG> routine returns the user's current erase
character.
The <STRONG>erasewchar</STRONG> routine stores the current erase character
in the location referenced by <EM>ch</EM>. If no erase character
has been defined, the routine fails and the location ref-
erenced by <EM>ch</EM> is not changed.
The <STRONG>has_ic</STRONG> routine is true if the terminal has insert- and
delete- character capabilities.
The <STRONG>has_il</STRONG> 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
<STRONG>scrollok</STRONG>.
The <STRONG>killchar</STRONG> routine returns the user's current line kill
character.
The <STRONG>killwchar</STRONG> routine stores the current line-kill charac-
ter in the location referenced by <EM>ch</EM>. If no line-kill
character has been defined, the routine fails and the
location referenced by <EM>ch</EM> is not changed.
The <STRONG>longname</STRONG> 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 charac-
ters. It is defined only after the call to <STRONG>initscr</STRONG> or
<STRONG>newterm</STRONG>. The area is overwritten by each call to <STRONG>newterm</STRONG>
and is not restored by <STRONG>set_term</STRONG>, so the value should be
saved between calls to <STRONG>newterm</STRONG> if <STRONG>longname</STRONG> is going to be
used with multiple terminals.
If a given terminal does not support a video attribute
that an application program is trying to use, <STRONG>curses</STRONG> may
substitute a different video attribute for it. The
<STRONG>termattrs</STRONG> and <STRONG>term_attrs</STRONG> functions return a logical <STRONG>OR</STRONG> of
all video attributes supported by the terminal using <EM>A</EM><STRONG>_</STRONG>
and <EM>WA</EM><STRONG>_</STRONG> constants respectively. This information is use-
ful when a <STRONG>curses</STRONG> program needs complete control over the
appearance of the screen.
The <STRONG>termname</STRONG> routine returns the terminal name used by
<STRONG>setupterm</STRONG>.
</PRE>
<H2>RETURN VALUE</H2><PRE>
<STRONG>longname</STRONG> and <STRONG>termname</STRONG> return <STRONG>NULL</STRONG> on error.
Routines that return an integer return <STRONG>ERR</STRONG> upon failure
and <STRONG>OK</STRONG> (SVr4 only specifies "an integer value other than
<STRONG>ERR</STRONG>") upon successful completion.
</PRE>
<H2>NOTES</H2><PRE>
Note that <STRONG>termattrs</STRONG> may be a macro.
</PRE>
<H2>PORTABILITY</H2><PRE>
The XSI Curses standard, Issue 4 describes these func-
tions. It changes the return type of <STRONG>termattrs</STRONG> to the new
type <STRONG>attr_t</STRONG>. Most versions of curses truncate the result
returned by <STRONG>termname</STRONG> to 14 characters.
