+ 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

+ mode by taking over up to two lines at the bottom of the
+ screen; it does not 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-
- fied, respectively, within the label.

+
+ <STRONG>0</STRONG> indicates a 3-2-3 arrangement of the labels.
+

+
+ <STRONG>3</STRONG> is again the PC-like 4-4-4 mode, but in addition
+ an index line is generated, helping the user to

+
+ The <STRONG>slk_set</STRONG> routine (and the <STRONG>slk_wset</STRONG> routine for the
+ wide-character library) has three parameters:
+
+ <EM>labnum</EM>
+ is the label number, from <STRONG>1</STRONG> to <STRONG>8</STRONG> (12 for <EM>fmt</EM>
+ in <STRONG>slk_init</STRONG> is <STRONG>2</STRONG> or <STRONG>3</STRONG>);
+
+ <EM>label</EM>
+ is be the string to put on the label, up to
+ eight (five for <EM>fmt</EM> in <STRONG>slk_init</STRONG> is <STRONG>2</STRONG> or <STRONG>3</STRONG>)

+ pointer sets up a blank label.
