curs_scroll(3CURSES)					     Curses Library Functions					      curs_scroll(3CURSES)

NAME

       curs_scroll, scroll, scrl, wscrl - scroll a curses window

SYNOPSIS

       cc [ flag ... ] file ... -lcurses [ library ... ]
       #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 optimiza-
       tion, 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 ERR upon failure and an integer value other than ERR upon successful completion.
