NAME
     curs_slk: slk_init, slk_set, slk_refresh, slk_noutrefresh,
          slk_label, slk_clear, slk_restore, slk_touch,

          label  routines

SYNOPSIS
     #include <curses.h>

     int slk_init(int fmt);

     int slk_set(int labnum, 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(chtype attrs);

     int slk_attrset(chtype attrs);
     int slk_attroff(chtype attrs);

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 stdscr and the variable LINES.
     curses standardizes on eight labels of up to eight charac-
     ters 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.  Set-
     ting 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-justified, 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 output 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 VALUE
     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.

NOTES
     The header file <curses.h> automatically includes the header
     files <stdio.h> and <unctrl.h>.

     Most applications would use slk_noutrefresh because a
     wrefresh is likely to follow soon.
