DESCRIPTION
curses manipulates the set of soft function-key labels that exist on
many terminals. For those terminals that do not have soft labels,
curses takes over the bottom line of stdscr, reducing the size of std‐
scr and the variable LINES. curses standardizes on eight labels of up
to eight characters each.
To use soft labels, the slk_init() routine must be called before
initscr() or newterm() is called. If initscr() eventually uses a line
from stdscr to emulate the soft labels, then fmt determines how the
labels are arranged on the screen. Setting fmt to 0 indicates a 3-2-3
arrangement of the labels; 1 indicates a 4-4 arrangement.
With the slk_set() routine, labnum is the label number, from 1 to 8.
label is the string to be put on the label, up to eight characters in
length. A null string or a null pointer sets up a blank label. fmt is
either 0, 1, or 2, indicating whether the label is to be left-justi‐
fied, centered, or right-justified, respectively, within the label.
The slk_refresh() and slk_noutrefresh() routines correspond to the
wrefresh() and wnoutrefresh() routines.
With the slk_label() routine, the current label for label number labnum
is returned with leading and trailing blanks stripped.
With the slk_clear() routine, the soft labels are cleared from the
screen.
With the slk_restore() routine, the soft labels are restored to the
screen after a slk_clear() is performed.
With the slk_touch() routine, all the soft labels are forced to be out‐
put the next time a slk_noutrefresh() is performed.
The slk_attron(), slk_attrset(), and slk_attroff() routines correspond
to attron(), attrset(), and attroff(). They have an effect only if soft
labels are simulated on the bottom line of the screen.
RETURN VALUES
Routines that return an integer return ERR upon failure and an integer
value other than ERR upon successful completion.
slk_label() returns NULL on error.

The header <curses.h> automatically includes the headers <stdio.h> and
<unctrl.h>.
Most applications would use slk_noutrefresh() because a wrefresh() is
likely to follow soon.
