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
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(), 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.

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