DESCRIPTION
These functions manipulate the attributes and color of the window ren‐
dition of the current or specified window. The current attributes of a
window are applied to all characters that are written into the window.
These attributes become property of the character and move with the
character through any scrolling and insert/delete line/character opera‐
tions. To the extent possible on the particular terminal, attributes
are displayed as the graphic rendition of characters put on the screen.
The attr_get and wattr_get functions obtain the window rendition of the
current or specified window. If attrs or color_pair is a null pointer,
the functions do not obtain corresponding rendition information; this
condition is not an error.
The attr_off and wattr_off functions turn off the named attributes,
without affecting other attributes, for the current or specified win‐
dow.
The attr_on and wattr_on functions turn on the named attributes, with‐
out affecting other attributes, for the current or specified window.
The attr_set and wattr_set functions set the window rendition of the
current or specified window in conjunction with the window background
rendition.
The color_set and wcolor_set functions set the window color of the cur‐
rent or specified window to color_pair.
The opts argument in all the preceding functions is reserved for future
use. Currently, applications must provide a null pointer for the opts
argument.
Attributes
Applications can pass the following video attributes, which are defined
in <curses.h>, to these routines in place of attrs to turn on or off
the corresponding attribute. More than one attribute can be passed by
using an inclusive OR operation.
WA_ALTCHARSET Alternate character set
WA_BLINK Blinking
WA_BOLD Extra bright or bold
WA_DIM Half bright
WA_HORIZONTAL Horizontal highlight
WA_INVIS Invisible
WA_LEFT Left highlight
WA_LOW Low highlight
WA_PROTECT Protected
WA_REVERSE Reverse video
WA_RIGHT Right highlight
WA_STANDOUT Best highlighting mode of the terminal.
WA_TOP Top highlight
WA_UNDERLINE Underlining
WA_VERTICAL Vertical highlight
NOTES
The header file <curses.h> automatically includes the header file
<stdio.h>.
Note that attr_get, attr_off, attr_on, attr_set, and color_set may be
macros.
RETURN VALUES
These routines always return OK.
