redrawwin(3XCURSES) X/Open Curses Library Functions redrawwin(3XCURSES) NAME
redrawwin, wredrawln - redraw screen or portion of screen 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 redrawwin(WINDOW *win); int wredrawln(WINDOW *win, int beg_line, int num_lines); PARAMETERS
win Is a pointer to the window in which to redraw. beg_line Is the first line to redraw. num_lines Is the number of lines to redraw. DESCRIPTION
The redrawwin() and wredrawln() functions force portions of a window to be redrawn to the terminal when the next refresh operation is per- formed. The redrawwin() function forces the entire window win to be redrawn, while the wredrawln() function forces only num_lines lines starting with beg_line to be redrawn. Normally, refresh operations use optimization methods to reduce the actual amount of the screen to redraw based on the current screen contents. These functions tell the refresh operations not to attempt any optimization when redrawing the indicated areas. These functions are useful when the data that exists on the screen is believed to be corrupt and for applications such as screen editors that redraw portions of the screen. RETURN VALUES
On success, these functions return OK. Otherwise, they return ERR. 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
