Curses Library Functions                     cursscroll(3CURSES)



NAME
     cursscroll, scroll, scrl, wscrl - scroll a curses window

SYNOPSIS
     cc [ flag ... ] file ... -lcurses [ library ... ]
     #include 

     int scroll(WINDOW *win);


     int scrl(int n);


     int wscrl(WINDOW *win, int n);


DESCRIPTION
     With the scroll() routine, the window  is  scrolled  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.


     With the scrl() and wscrl() routines, for positive n  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 cursor
     position is not changed.


     For these functions to work, scrolling must be  enabled  via
     scrollok().

RETURN VALUES
     All routines return the integer  ER  upon  failure  and  an
     integer value other than ER upon successful completion.
