       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 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-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 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.

      NOTICES
            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.
