NAME

attroff, attron, attrset, wattroff, wattron, wattrset - change foreground 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 specified attributes for window win.

The attrset() and wattrset() functions change the specified window renditions 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 rendition, 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();
