NAME
redrawwin, wredrawln — line update status functions
SYNOPSIS
#include <curses.h>
int redrawwin(WINDOW *win);
int wredrawln(WINDOW *win, int beg_line, int num_lines);
DESCRIPTION
The redrawwin() and wredrawln() functions inform the implementation that some or all of the
information physically displayed for the specified window may have been corrupted. The redrawwin()
function marks the entire window; wredrawln() marks only num_lines lines starting at line number
beg_line. The functions prevent the next refresh operation on that window from performing any optimisa-
tion based on assumptions about what is physically displayed there.
RETURN VALUE
Upon successful completion, these functions return OK. Otherwise they return ERR.
ERRORS
No errors are defined.
APPLICATION USAGE
The redrawwin() and wredrawln() functions could be used in a text editor to implement a command
that redraws some or all of the screen.
