-<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>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>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 doesn't support a video attribute that
- an application program is trying to use, <STRONG>curses</STRONG> may sub-
- stitute a different video attribute for it. The <STRONG>termattrs</STRONG>
- function returns a logical <STRONG>OR</STRONG> of all video attributes sup-
- ported by the terminal. This information is useful when a
- <STRONG>curses</STRONG> program needs complete control over the appearance
- of the screen.
-
-
-
-</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>.
