curs_scroll(3X)                   SDK R4.11                  curs_scroll(3X)


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

SYNOPSIS
       #include <curses.h>

       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 VALUE
       All routines return the integer ERR upon failure and an integer value
       other than ERR upon successful completion.

NOTES
       The header file <curses.h> automatically includes the header files
       <stdio.h> and <unctrl.h>.

       Note that scrl and scroll may be macros.
