Synopsis
cc [flag . . .] file -locurses [library . . .]
#include <ocurses.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.
