curs_scroll(3X)         LIBRARY FUNCTIONS         curs_scroll(3X)



NAME
     cursscroll:  scroll, srcl, 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.
