curs_slk(3)                                           curs_slk(3)

       slk_init,     slk_set,    slk_refresh,    slk_noutrefresh,
       slk_label, slk_clear, slk_restore, slk_touch,  slk_attron,
       slk_attrset,  slk_attroff,  slk_color  - curses soft label

       #include <curses.h>

       int slk_init(int fmt);
       int slk_set(int labnum, const char *label, int fmt);
       int slk_refresh(void);
       int slk_noutrefresh(void);
       char *slk_label(int labnum);
       int slk_clear(void);
       int slk_restore(void);
       int slk_touch(void);
       int slk_attron(const chtype attrs);
       int slk_attrset(const chtype attrs);
       attr_t slk_attr(void);
       int slk_attroff(const chtype attrs);
       int slk_color(short color_pair_number);

       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, curses takes over the bottom
       line  of stdscr, reducing the size of stdscr and the vari-
       able LINES.  curses 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  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 and 2 indicates the PC like 4-4-4 mode. If
       fmt  is  set to 3, 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  slk_set routine requires labnum to be a label number,
       from 1 to 8 (resp. 12); label 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.  fmt  is  either 0, 1, or 2, indicating whether the
       label is  to be left-justified, centered, or  right-justi-
       fied, respectively, within the label.


curs_slk(3)                                           curs_slk(3)

       The slk_refresh and slk_noutrefresh routines correspond to
       the wrefresh and wnoutrefresh routines.

       The slk_label routine returns the current label for  label
       number  labnum, with leading and trailing blanks stripped.

       The slk_clear routine clears  the  soft  labels  from  the

       The  slk_restore  routine, restores the soft labels to the
       screen after a slk_clear has been performed.

       The slk_touch routine forces all the  soft  labels  to  be
       output the next time a slk_noutrefresh is performed.

       The slk_attron, slk_attrset, slk_attroff and slk_attr rou-
       tines correspond to attron, attrset, attroff and attr_get.
       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 slk_color routine corresponds to color_set. It has  an
       effect  only  if  soft  labels are simulated on the bottom
       line of the screen.

       These routines return ERR upon failure and OK (SVr4 speci-
       fies only "an integer value other than ERR") upon success-
       ful completion. slk_attr returns the  attribute  used  for
       the soft keys.

       slk_label returns NULL on error.

       Most applications would use slk_noutrefresh because a wre-
       fresh is likely to follow soon.

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