CURSES_SCROLL(3)           Library Functions Manual           CURSES_SCROLL(3)

     curses_scroll, scrl, wscrl scroll, scrollok, setscrreg, wsetscrreg --
     curses window scrolling routines

     Curses Library (libcurses, -lcurses)

     #include <curses.h>

     scrl(int n);

     wscrl(WINDOW *win, int n);

     scroll(WINDOW *win);

     scrollok(WINDOW *win, boolf flag);

     setscrreg(int top, int bottom);

     wsetscrreg(WINDOW *win, int top, int bottom);

     These functions scroll areas on stdscr or on the specified window.

     The scrl() function scrolls stdscr by n lines.  If n is positive then
     then stdscr is scrolled up.  n lines are lost from the top of stdscr and
     n blank lines are inserted at the bottom.  If n is negative then stdscr
     is scrolled down.  n blank lines are inserted at the top of stdscr and n
     lines are lost from the bottom.

     The wscrl() function is the same as the scrl() function, excepting that
     it scrolls the window specified by win.

     The scroll() function scrolls the window win up by one line.

     The scrolling behaviour of a window can be controlled by using the
     scrollok() function.  If the flag argument is TRUE then a line wrap at
     the bottom of the window will cause the window to be scrolled up one
     line, if flag is FALSE then lines that would force a scroll will be

     The setscrreg() function sets up a software scrolling region on stdscr
     which will define a region of the screen that will be scrolled.  The
     scrolling of this region is also controlled by the scrollok() function.

     The wsetscrreg() function does the same as the setscrreg() function,
     except that the scrolling region is set on the window specified by win.

     If a scrolling region has been set with the setscrreg() or wsetscrreg()
     functions and the current cursor position is inside the scrolling region,
     then only the area inside the scrolling region is scrolled.

     Functions returning pointers will return NULL if an error is detected.
     The functions that return an int will return one of the following values:

     OK   The function completed successfully.
     ERR  An error occurred in the function.
