int syncok(WINDOW *win, bool bf);
void wcursyncup(WINDOW *win);
void wsyncdown(WINDOW *win);
void wsyncup(WINDOW *win);

Parameters

win

Is a pointer to a window.

bf

Is a Boolean expression.

Description

The syncok() function uses the value of bf to determine whether or not the window win's ancestors are implicitly touched whenever there is a change to win. If bf is TRUE, this touching occurs. If bf is FALSE, it does not occur. The initial value for bf is FALSE.

The wcursyncup() function moves the cursor in win's ancestors to match its position in win.

The wsyncdown() function touches win if any of its ancestors have been touched.

The wsyncup() function touches all ancestors of win.

Return Values

On success, the syncok() function returns OK. Otherwise, it returns ERR.

The other functions do not return a value.

Errors

None.
