refresh, wrefresh, doupdate, wnoutrefresh
The refresh set of routines is used to copy a window data structure to a
physical window.
Syntax
#include <curses.h>
int refresh();
int wrefresh(WINDOW *win);
int doupdate();
int wnoutrefresh(WINDOW *win);
Parameters
win A pointer to the window in which to refresh.
Return Values
OK Successful completion.
ERROR An error occurred.
Description
The refresh() and wrefresh() routines copy stdscr and win, respectively,
to the terminal screen. These routines call the wnoutrefresh() routine
to copy the specified window to curscr and the doupdate() routine 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()
is enabled (in which case, the cursor is placed in a position that CURSES
finds convenient).
When outputting several windows at once, it is often more efficient to
call the wnoutrefresh() and doupdate() routines directly. A call to
wnoutrefresh()for each window first, 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 global variable curscr, the screen
is immediately cleared and repainted from scratch.
Implementation Considerations
Identical to XPG/3
