74        The  <STRONG>baudrate</STRONG>  routine  returns  the output speed of the terminal.  The
75        number returned is in bits per second, for  example  <STRONG>9600</STRONG>,  and  is  an
76        integer.

78
79 </PRE><H3><a name="h3-erasechar_-erasewchar">erasechar, erasewchar</a></H3><PRE>
80        The <STRONG>erasechar</STRONG> routine returns the user's current erase character.
81
82        The  <STRONG>erasewchar</STRONG>  routine  stores  the  current  erase  character in the
83        location referenced by <EM>ch</EM>.  If no erase character has been defined, the
84        routine fails and the location referenced by <EM>ch</EM> is not changed.

87 </PRE><H3><a name="h3-has_is_-has_il">has_is, has_il</a></H3><PRE>
88        The  <STRONG>has_ic</STRONG>  routine  is  true  if the terminal has insert- and delete-
89        character capabilities.
90
91        The <STRONG>has_il</STRONG> routine is true if the terminal has insert- and  delete-line
92        capabilities, or can simulate them using scrolling regions.  This might
93        be used to determine if it would be appropriate  to  turn  on  physical
94        scrolling using <STRONG>scrollok</STRONG>.

97 </PRE><H3><a name="h3-killchar_-killwchar">killchar, killwchar</a></H3><PRE>
98        The <STRONG>killchar</STRONG> routine returns the user's current line kill character.
99
100        The  <STRONG>killwchar</STRONG>  routine  stores  the current line-kill character in the
101        location referenced by <EM>ch</EM>.  If no line-kill character has been defined,
102        the routine fails and the location referenced by <EM>ch</EM> is not changed.

104
105 </PRE><H3><a name="h3-longname">longname</a></H3><PRE>
106        The  <STRONG>longname</STRONG>  routine  returns a pointer to a static area containing a
107        verbose description of the current terminal.  The maximum length  of  a
108        verbose  description  is  128 characters.  It is defined only after the
109        call to <STRONG>initscr</STRONG> or <STRONG>newterm</STRONG>.  The area is overwritten by  each  call  to
110        <STRONG>newterm</STRONG>  and  is not restored by <STRONG>set_term</STRONG>, so the value should be saved
111        between calls to <STRONG>newterm</STRONG> if <STRONG>longname</STRONG> is going to be used with  multiple
112        terminals.

116        If  a  given  terminal  does  not  support  a  video  attribute that an
117        application program is trying to use, <STRONG>curses</STRONG> may substitute a different
118        video  attribute for it.  The <STRONG>termattrs</STRONG> and <STRONG>term_attrs</STRONG> functions return
119        a logical <STRONG>OR</STRONG> of all video attributes supported by the terminal using <STRONG>A_</STRONG>
120        and  <STRONG>WA_</STRONG>  constants  respectively.   This  information is useful when a
121        <STRONG>curses</STRONG> program needs  complete  control  over  the  appearance  of  the
122        screen.
123
124
125 </PRE><H3><a name="h3-termname">termname</a></H3><PRE>
126        The <STRONG>termname</STRONG> routine returns the terminal name used by <STRONG>setupterm</STRONG>.

130        <STRONG>longname</STRONG> and <STRONG>termname</STRONG> return <STRONG>NULL</STRONG> on error.
131
132        Routines  that  return  an integer return <STRONG>ERR</STRONG> upon failure and <STRONG>OK</STRONG> (SVr4
133        only specifies "an integer  value  other  than  <STRONG>ERR</STRONG>")  upon  successful
134        completion.

142        The XSI Curses standard, Issue 4 describes these functions.  It changes
143        the return type of <STRONG>termattrs</STRONG> to the new type <STRONG>attr_t</STRONG>.  Most versions  of
144        curses truncate the result returned by <STRONG>termname</STRONG> to 14 characters.
