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.

Notes

The header <curses.h> automatically includes the headers <stdio.h> and <unctrl.h>.

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