curs_scroll(3)
NAME
  curs_scroll, scroll, scrl, wscrl - Scroll a Curses window

LIBRARY
  Curses Library (libcurses.a, libcurses.so)

SYNOPSIS
  #include <curses.h>

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

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

  scroll:  XPG4, XPG4-UNIX

  scrl, wscrl:	XPG4-UNIX

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

DESCRIPTION
  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
  The header file curses.h automatically includes the header file stdio.h.

  Note that scrl may be a macro.




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