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.
