clrtoeol(3XCURSES) X/Open Curses Library Functions clrtoeol(3XCURSES)NAME
clrtoeol, wclrtoeol - clear to the end of a line
SYNOPSIS
cc [ flag... ] file... -I /usr/xpg4/include -L /usr/xpg4/lib
-R /usr/xpg4/lib -lcurses [ library... ]
c89 [ flag... ] file... -lcurses [ library... ]
#include <curses.h>
int clrtoeol(void);
int wclrtoeol(WINDOW *win);
DESCRIPTION
The clrtoeol() function clears the current line from the cursor to the right margin in the stdscr window. The wclrtoeol() function per-
forms the same action, but in the window specified by win instead of stdscr. The current background character (and rendition) is used to
clear the screen.
If the clearing action results in clearing only a portion of a multicolumn character, background characters are displayed in place of the
remaining portion.
PARAMETERS
win Is a pointer to the window in which to clear to the end of the line.
RETURN VALUES
On success, these functions return OK. Otherwise, they return FALSE.
ERRORS
None.

bkgd(3XCURSES) X/Open Curses Library Functions bkgd(3XCURSES)NAME
bkgd, bkgdset, getbkgd, wbkgd, wbkgdset - set or get the background character (and rendition) of window
SYNOPSIS
cc [ flag... ] file... -I /usr/xpg4/include -L /usr/xpg4/lib
-R /usr/xpg4/lib -lcurses [ library... ]
c89 [ flag... ] file... -lcurses [ library... ]
#include <curses.h>
int bkgd(chtype ch);
void bkgdset(chtype ch);
chtype getbkgd(WINDOW *win);
int wbkgd(WINDOW *win, chtype ch);
void wbkgdset(WINDOW *win, chtype ch);
DESCRIPTION
The bkgdset() and wbkgdset() functions turn off the previous background attributes, logical OR the requested attributes into the window
rendition, and set the background property of the current or specified window based on the information in ch. If ch refers to a multi-col-
umn character, the results are undefined.
The bkgd() and wbkgd() functions turn off the previous background attributes, logical OR the requested attributes into the window rendi-
tion, and set the background property of the current or specified window and then apply this setting to every character position in that
window:
o The rendition of every character on the screen is changed to the new window rendition.
o Wherever the former background character appears, it is changed to the new background character.
The getbkgd() function extracts the specified window's background character and rendition.
PARAMETERS
ch Is the background character to be set.
win Is a pointer to the window in which the background character is to be set.
RETURN VALUES
Upon successful completion, the bkgd() and wbkgd() functions return OK. Otherwise, they return ERR.
The bkgdset() and wbkgdset() functions do not return a value.
Upon successful completion, the getbkgd() function returns the specified window's background character and rendition. Otherwise, it returns
(chtype)ERR.
ERRORS
No errors are defined.
USAGE
These functions are only guaranteed to operate reliably on character sets in which each character fits into a single byte, whose attributes
can be expressed using only constants with the A_ prefix.
