-<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, <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
- for todays PC like enduser devices. Please note that
- ncurses simulates this mode by taking over up to two lines
- at the bottom of the screen, it doesn't try to use any
- hardware support for this mode.
-
- The <STRONG>slk_init</STRONG> routine must be called before <STRONG>initscr</STRONG> or
- <STRONG>newterm</STRONG> is called. If <STRONG>initscr</STRONG> eventually uses a line from
- <STRONG>stdscr</STRONG> to emulate the soft labels, then <EM>fmt</EM> determines how
- the labels are arranged on the screen. Setting <EM>fmt</EM> to <STRONG>0</STRONG>
- indicates a 3-2-3 arrangement of the labels, <STRONG>1</STRONG> indicates a
- 4-4 arrangement and <STRONG>2</STRONG> indicates the PC like 4-4-4 mode. If
- <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 <STRONG>slk_set</STRONG> routine requires <EM>labnum</EM> to be a label number,
- from <STRONG>1</STRONG> to <STRONG>8</STRONG> (resp. <STRONG>12</STRONG>); <EM>label</EM> must be the string to be put
- on the label, up to eight (resp. five) characters in
- length. A null string or a null pointer sets up a blank
- label. <EM>fmt</EM> is either <STRONG>0</STRONG>, <STRONG>1</STRONG>, or <STRONG>2</STRONG>, indicating whether the
- label is to be left-justified, centered, or right-justi-
- the <STRONG>wrefresh</STRONG> and <STRONG>wnoutrefresh</STRONG> routines.
-
- The <STRONG>slk_label</STRONG> routine returns the current label for label
- number <EM>labnum</EM>, with leading and trailing blanks stripped.
-
- The <STRONG>slk_clear</STRONG> routine clears the soft labels from the
- screen.
-
- The <STRONG>slk_restore</STRONG> routine, restores the soft labels to the
- screen after a <STRONG>slk_clear</STRONG> has been performed.
-
- The <STRONG>slk_touch</STRONG> routine forces all the soft labels to be
- output the next time a <STRONG>slk_noutrefresh</STRONG> is performed.
-
- The <STRONG>slk_attron</STRONG>, <STRONG>slk_attrset</STRONG>, <STRONG>slk_attroff</STRONG> and <STRONG>slk_attr</STRONG> rou-
- tines correspond to <STRONG>attron</STRONG>, <STRONG>attrset</STRONG>, <STRONG>attroff</STRONG> and <STRONG>attr_get</STRONG>.
- They have an effect only if soft labels are simulated on
- the bottom line of the screen. The default highlight for
- soft keys is A_STANDOUT (as in System V curses, which does
- not document this fact).
-
- The <STRONG>slk_color</STRONG> routine corresponds to <STRONG>color_set</STRONG>. It has an
- effect only if soft labels are simulated on the bottom
- line of the screen.

-<H2>RETURN VALUE</H2><PRE>
- These routines return <STRONG>ERR</STRONG> upon failure and OK (SVr4 speci-
- fies only "an integer value other than <STRONG>ERR</STRONG>") upon success-
- ful completion. <STRONG>slk_attr</STRONG> returns the attribute used for
- the soft keys.
-
- <STRONG>slk_label</STRONG> returns <STRONG>NULL</STRONG> on error.
-
-
-</PRE>
-<H2>NOTES</H2><PRE>
- Most applications would use <STRONG>slk_noutrefresh</STRONG> because a <STRONG>wre-</STRONG>
- <STRONG>fresh</STRONG> is likely to follow soon.

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