# DESCRIPTION
|
|
|
|
|
|
|
|
**ncplane_format** sets the attributes of every cell in the region having its
|
|
|
|
upper-left corner at the cursor's current position, and its lower-right corner
|
|
|
|
at **ystop**, **xstop**.
|
|
|
|
|
|
|
|
Box- and line-drawing is unaffected by a plane's scrolling status.
|
|
|
|
|
|
|
|
# RETURN VALUES
|
|
|
|
|
|
|
|
**ncplane_format** returns -1 if either **ystop** or **xstop** is less than the
|
|
|
|
current equivalent position, otherwise 0.
