NAME
       cursslk:  slkinit, slkset, slkrefresh, slknoutrefresh,
       slklabel, slkclear, slkrestore, slktouch, slkattron,
       slkattrset, slkattroff - curses soft label  routines

SYNOPSIS
       #include <curses.h>

       int slkinit(int fmt);
       int slkset(int labnum, char *label, int fmt);
       int slkrefresh(void);
       int slknoutrefresh(void);
       char *slklabel(int labnum);
       int slkclear(void);
       int slkrestore(void);
       int slktouch(void);
       int slkattron(chtype attrs);
       int slkattrset(chtype attrs);
       int slkattroff(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 characters each.

       To use soft labels, the slkinit 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 slkset 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 slkrefresh and slknoutrefresh routines correspond to the
       wrefresh and wnoutrefresh routines.

       With the slklabel routine, the current label for label number labnum
       is returned with leading and trailing blanks stripped.

       With the slkclear routine, the soft labels are cleared from the
       screen.

       With the slkrestore routine, the soft labels are restored to the
       screen after a slkclear is performed.

       With the slktouch routine, all the soft labels are forced to be
       output the next time a slknoutrefresh is performed.

       The slkattron, slkattrset and slkattroff 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.

       slklabel returns NULL on error.

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

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