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.
