X/Open Curses Library Functions                              attroff(3XCURSES)



NAME
       attroff,  attron,  attrset,  wattroff, wattron, wattrset - change fore‐
       ground window attributes

SYNOPSIS
       cc [ flag... ] file... -I /usr/xpg4/include -L /usr/xpg4/lib \
       -R /usr/xpg4/lib -lcurses [ library... ]

       c89 [ flag... ] file... -lcurses [ library... ]

       #include <curses.h>

       int attroff(int attrs);


       int attron(int attrs);


       int attrset(int attrs);


       int wattroff(WINDOW *win, int attrs);


       int wattron(WINDOW *win, int attrs);


       int wattrset(WINDOW *win, int attrs);

DESCRIPTION
       The attroff() and attron() functions unset and set,  respectively,  the
       specified  window attributes of stdscr. These functions only affect the
       attributes specified; attributes  that  existed  before  the  call  are
       retained. The wattroff() and wattron() functions unset or set the spec‐
       ified attributes for window win.


       The attrset() and wattrset() functions change the specified window ren‐
       ditions  of  stdscr  and  win  to  new  values;  the old values are not
       retained.


       The attributes that can be used are specified in the Attributes,  Color
       Pairs, and Renditions section of the curses(3XCURSES) man page.


       Here  is an example that prints some text using the current window ren‐
       dition, adds underlining, changes the  attributes,  prints  more  text,
       then changes the attributes back.

         printw("This word is");
         attron(A_UNDERLINE);
         printw("underlined.");
         attroff(A_NORMAL);
         printw("This is back to normal text.\n");
         refresh();


PARAMETERS
       attrs    are the foreground window attributes to be set or unset.


       win      Is  a  pointer to the window in which attribute changes are to
                be made.


RETURN VALUES
       These functions always return OK or 1.

ERRORS
       None.
