curs_attr(3X)                     SDK R4.11                    curs_attr(3X)


NAME
       curs_attr:  attroff, wattroff, attron, wattron, attrset, wattrset,
       standend, wstandend, standout, wstandout - curses character and
       window attribute control routines

SYNOPSIS
       #include <curses.h>
       int attroff(chtype attrs);
       int wattroff(WINDOW *win, chtype attrs);
       int attron(chtype attrs);
       int wattron(WINDOW *win, chtype attrs);
       int attrset(chtype attrs);
       int wattrset(WINDOW *win, chtype attrs);
       int standend(void);
       int wstandend(WINDOW *win);
       int standout(void);
       int wstandout(WINDOW *win);

DESCRIPTION
       All of these routines manipulate the current attributes of the named
       window.  The current attributes of a window are applied to all
       characters that are written into the window with waddch, waddstr and
       wprintw.  Attributes are a property of the character, and move with
       the character through any scrolling and insert/delete line/character
       operations.  To the extent possible on the particular terminal, they
       are displayed as the graphic rendition of characters put on the
       screen.

       The routine attrset sets the current attributes of the given window
       to attrs.  The routine attroff turns off the named attributes without
       turning any other attributes on or off.  The routine attron turns on
       the named attributes without affecting any others.  The routine
       standout is the same as attron(A_STANDOUT).  The routine standend is
       the same as attrset(0), that is, it turns off all attributes.

   Attributes
       The following video attributes, defined in <curses.h>, can be passed
       to the routines attron, attroff, and attrset, or OR-ed with the
       characters passed to addch.

              A_STANDOUT     Best highlighting mode of the terminal.
              A_UNDERLINE    Underlining
              A_REVERSE      Reverse video
              A_BLINK        Blinking
              A_DIM          Half bright
              A_BOLD         Extra bright or bold
              A_ALTCHARSET   Alternate character set
              A_CHARTEXT     Bit-mask to extract a character
              COLOR_PAIR(n)  Color-pair number n

       The following macro is the reverse of COLOR_PAIR(n):

              PAIR_NUMBER(attrs)Returns the pair number associated
                             with the COLOR_PAIR(n) attribute.

RETURN VALUE
       These routines always return 1.

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

       Note that attroff, wattroff, attron, wattron, attrset, wattrset,
       standend and standout may be macros.
