- curses soft label routines
cc [ flag ... ] file ... -lcurses [ library ... ] #include <curses.h> int slk_init(int fmt);
int slk_set(int labnum, char *label, int fmt);
char *slk_label(int labnum);

int slk_attrset(chtype attrs);
int slk_attroff(chtype attrs);
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.
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.
See attributes(5) for descriptions of the following attributes:
The header <curses.h> automatically includes the headers <stdio.h> and <unctrl.h>.
Most applications would use slk_noutrefresh() because a wrefresh() is likely to follow soon.
