Updates the terminal's display and the curscr to reflect changes made to a window.
Curses Library (libcurses.a)
wrefresh(Window) WINDOW *Window;
The refresh or wrefresh subroutines update the terminal and the curscr to reflect changes made to a window. The refresh subroutine updates the stdscr. The wrefresh subroutine refreshes a user-defined window.
Other subroutines manipulate windows but do not update the terminal's physical display to reflect their changes. Use the refresh or wrefresh subroutines to update a terminal's display after internal window representations change. Both subroutines check for possible scroll errors at display time.
Note: The physical terminal cursor remains at the location of the window's cursor during a refresh, unless the leaveok subroutine is enabled.
The refresh and wrefresh subroutines call two other subroutines to perform the refresh operation. First, the wnoutrefresh subroutine copies the designated window structure to the terminal. Then, the doupdate subroutine updates the terminal's display and the cursor.
|Window||Specifies the window to refresh.|
WINDOW *my_window; wrefresh(my_window);
wrefresh(curscr);This subroutine is useful if the terminal becomes garbled for any reason.
These subroutines are part of Base Operating System (BOS) Runtime.
The doupdate subroutine, leaveok subroutine, wnoutrefresh subroutine.
