     #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    [Toc]    [Back]

     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 VALUE    [Toc]    [Back]

     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    [Toc]    [Back]

     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.
