## DESCRIPTION

```-       The  scroll  routine scrolls the window up one line.  This
-       involves moving the lines in the  window  data  structure.
-       As  an optimization, if the scrolling region of the window
-       is the entire screen, the physical screen may be  scrolled
-       at the same time.
+       The  scroll routine scrolls the window up one line.  This involves mov-
+       ing the lines in the window data structure.  As an optimization, if the
+       scrolling  region  of  the  window  is  the entire screen, the physical
+       screen may be scrolled at the same time.

-       For  positive  n,  the  scrl and wscrl routines scroll the
-       window up n lines (line i+n becomes i);  otherwise  scroll
-       the  window  down n lines.  This involves moving the lines
-       in the window character image structure.  The current cur-
-       sor position is not changed.

-       For these functions to work, scrolling must be enabled via

## RETURN VALUE

```-       These routines return ERR upon failure, and OK (SVr4  only
-       specifies "an integer value other than ERR") upon success-
-       ful completion.
+       These routines return ERR upon failure, and OK (SVr4 only specifies "an
+       integer value other than ERR") upon successful completion.

X/Open defines no error conditions.

-       This implementation returns an error if the window pointer
-       is  null,  or  if  scrolling is not enabled in the window,
-       e.g., with scrollok.

## NOTES

```        Note that scrl and scroll may be macros.

-       The SVr4 documentation says that the optimization of phys-
-       ically  scrolling  immediately if the scroll region is the
-       entire screen "is"  performed,  not  "may  be"  performed.
-       This  implementation  deliberately does not guarantee that
-       this will occur, to leave open the possibility of  smarter
-       optimization  of  multiple  scroll actions on the next up-
-       date.

+       does not guarantee that this will occur, to leave open the  possibility
+       of smarter optimization of multiple scroll actions on the next update.

-       Neither the SVr4 nor the XSI documentation specify whether
-       the current attribute or current color-pair of blanks gen-
-       erated by the scroll function is zeroed.  Under  this  im-
-       plementation it is.

## PORTABILITY

```-       The  XSI  Curses  standard,  Issue 4 describes these func-
-       tions.
