curs_attr(3CURSES) Curses Library Functions curs_attr(3CURSES)NAME
curs_attr, attroff, wattroff, attron, wattron, attrset, wattrset,
standend, wstandend, standout, wstandout - curses character and window
attribute control routines
SYNOPSIS
cc [ flag ... ] file ... -lcurses [ library ... ]
#include <curses.h>
int attroff(int attrs);
int wattroff(WINDOW *win, int attrs);
int attron(int attrs);
int wattron(WINDOW *win, int attrs);
int attrset(int attrs);
int wattrset(WINDOW *win, int 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 charac‐
ters 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 stand‐
out() is the same as attron(A_STANDOUT). The routine standend() is the
same as attrset(), 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 VALUES
These routines always return 1.
