<H2>DESCRIPTION</H2><PRE>
The slk* functions manipulate the set of soft function-key
labels that exist on many terminals. For those terminals
- that do not have soft labels, <B>curses</B> takes over the bottom
- line of <B>stdscr</B>, reducing the size of <B>stdscr</B> and the vari-
- able <B>LINES</B>. <B>curses</B> standardizes on eight labels of up to
+ that do not have soft labels, <STRONG>curses</STRONG> takes over the bottom
+ line of <STRONG>stdscr</STRONG>, reducing the size of <STRONG>stdscr</STRONG> and the vari-
+ able <STRONG>LINES</STRONG>. <STRONG>curses</STRONG> standardizes on eight labels of up to
eight characters each. In addition to this, the ncurses
implementation supports a mode where it simulates 12
labels of up to five characters each. This is most common
at the bottom of the screen, it doesn't try to use any
hardware support for this mode.
- The <B>slk_init</B> routine must be called before <B>initscr</B> or
- <B>newterm</B> is called. If <B>initscr</B> eventually uses a line from
- <B>stdscr</B> to emulate the soft labels, then <I>fmt</I> determines how
- the labels are arranged on the screen. Setting <I>fmt</I> to <B>0</B>
- indicates a 3-2-3 arrangement of the labels, <B>1</B> indicates a
- 4-4 arrangement and <B>2</B> indicates the PC like 4-4-4 mode. If
- <B>fmt</B> is set to <B>3</B>, it is again the PC like 4-4-4 mode, but

+ <STRONG>fmt</STRONG> is set to <STRONG>3</STRONG>, it is again the PC like 4-4-4 mode, but
in addition an index line is generated, helping the user
to identify the key numbers easily.
- The <B>slk_set</B> routine requires <I>labnum</I> to be a label number,

length. A null string or a null pointer sets up a blank

They have an effect only if soft labels are simulated on
the bottom line of the screen. The default highlight for

not document this fact).

<H2>PORTABILITY</H2><PRE>
The XSI Curses standard, Issue 4, describes these func-
tions. It changes the argument type of the attribute-
- manipulation functions <B>slk_attron</B>, <B>slk_attroff</B>,
- <B>slk_attrset</B> to be <B>attr_t</B>, and adds <B>const</B> qualifiers. The
- format codes <B>2</B> and <B>3</B> for <B>slk_init()</B> and the function
- <B>slk_attr</B> are specific to ncurses.
