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

80 The <B>erasechar</B> routine returns the user's current erase character.
82 The <B>erasewchar</B> routine stores the current erase character in the
83 location referenced by <I>ch</I>. If no erase character has been defined, the
84 routine fails and the location referenced by <I>ch</I> is not changed.

88 The <B>has_ic</B> routine is true if the terminal has insert- and delete-
89 character capabilities.
91 The <B>has_il</B> 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 <B>scrollok</B>.

98 The <B>killchar</B> routine returns the user's current line kill character.
100 The <B>killwchar</B> routine stores the current line-kill character in the
101 location referenced by <I>ch</I>. If no line-kill character has been defined,
102 the routine fails and the location referenced by <I>ch</I> is not changed.

106 The <B>longname</B> 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 <B>initscr</B> or <B>newterm</B>. The area is overwritten by each call to
110 <B>newterm</B> and is not restored by <B>set_term</B>, so the value should be saved
111 between calls to <B>newterm</B> if <B>longname</B> is going to be used with multiple

116 If a given terminal does not support a video attribute that an
117 application program is trying to use, <B>curses</B> may substitute a different
118 video attribute for it. The <B>termattrs</B> and <B>term_attrs</B> functions return
119 a logical <B>OR</B> of all video attributes supported by the terminal using <I>A</I><B>_</B>
120 and <I>WA</I><B>_</B> constants respectively. This information is useful when a

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