NAME    [Toc]    [Back]

       curs_scroll, scroll, scrl, wscrl - Scroll a Curses window

SYNOPSIS    [Toc]    [Back]

       #include <curses.h>

       int scroll(
               WINDOW *win ); int scrl(
               int n ); int wscrl(
               WINDOW *win,
               int n );

LIBRARY    [Toc]    [Back]

       Curses Library (libcurses)

STANDARDS    [Toc]    [Back]

       Interfaces  documented  on  this reference page conform to
       industry standards as follows:

       scrl, wscrl, scroll:  XCURSES4.2

       Refer to the standards(5) reference page for more information
 about industry standards and associated tags.

DESCRIPTION    [Toc]    [Back]

       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 is scrolled at  the
       same time.

       The  scrl  and  wscrl routines, for positive n, scroll the
       current or specified window up n lines (line  i+n  becomes
       line  i); otherwise, these routines scroll the window down
       n lines. This operation involves moving the lines  in  the
       window  character-image  structure.  The  routines  do not
       change the current cursor position.

       For the scroll, scrl, and wscrl  functions  to  work,  the
       scrollok option must be enabled.

NOTES    [Toc]    [Back]

       The  header  file  <curses.h>  automatically  includes the
       header file <stdio.h>.

       Note that scrl may be a macro.

RETURN VALUES    [Toc]    [Back]

       All routines return the integer ERR upon  failure  and  OK
       upon successful completion.
