syncok(3XCURSES) X/Open Curses Library Functions syncok(3XCURSES) NAME
syncok, wcursyncup, wsyncdown, wsyncup - synchronize window with its parents or children 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 syncok(WINDOW *win, bool bf); void wcursyncup(WINDOW *win); void wsyncdown(WINDOW *win); void wsyncup(WINDOW *win); PARAMETERS
win Is a pointer to a window. bf Is a Boolean expression. DESCRIPTION
The syncok() function uses the value of bf to determine whether or not the window win's ancestors are implicitly touched whenever there is a change to win. If bf is TRUE, this touching occurs. If bf is FALSE, it does not occur. The initial value for bf is FALSE. The wcursyncup() function moves the cursor in win's ancestors to match its position in win. The wsyncdown() function touches win if any of its ancestors have been touched. The wsyncup() function touches all ancestors of win. RETURN VALUES
On success, the syncok() function returns OK. Otherwise, it returns ERR. The other functions do not return a value. ERRORS
None. ATTRIBUTES

doupdate(3XCURSES) X/Open Curses Library Functions doupdate(3XCURSES) NAME
doupdate, refresh, wnoutrefresh, wrefresh - refresh windows and lines 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 doupdate(void); int refresh(void); int wnoutrefresh(WINDOW *win); int wrefresh(WINDOW *win); DESCRIPTION
The refresh() and wrefresh() functions copy stdscr and win, respectively, to the terminal screen. These functions call the wnoutrefresh() function to copy the specified window to curscr and the doupdate() function to do the actual update. The physical cursor is mapped to the same position as the logical cursor of the last window to update curscr unless leaveok(3XCURSES) is enabled (in which case, the cur- sor is placed in a position that X/Open Curses finds convenient). When outputting several windows at once, it is often more efficient to call the wnoutrefresh() and doupdate() functions directly. A call to wnoutrefresh() for each window, followed by only one call to doupdate() to update the screen, results in one burst of output, fewer characters sent, and less CPU time used. If the win parameter to wrefresh() is the global variable curscr, the screen is immediately cleared and repainted from scratch. For details on how the wnoutrefresh() function handles overlapping windows with broad glyphs, see the Overlapping Windows section of the curses(3XCURSES) reference manual page. PARAMETERS
win Is a pointer to the window in which to refresh. RETURN VALUES
On success, these functions return OK. Otherwise, they return ERR. ERRORS
None. ATTRIBUTES
