scrollok - enable screen scrolling
int scrollok(win, bf)
This option controls what happens when the cursor is moved off the edge of the specified window or scrolling region, either from a newline
on the bottom line, or typing the last character of the last line. If disabled, (bf is FALSE) the cursor is left on the bottom line. If
enabled, the window is scrolled up one line and then refreshed.
The function returns OK on success and ERR on error.

CURSES_SCROLL(3) BSD Library Functions Manual CURSES_SCROLL(3)NAME
curses_scroll, scrl, wscrl scroll, scrollok, setscrreg, wsetscrreg -- curses window scrolling routines
Curses Library (libcurses, -lcurses)
wscrl(WINDOW *win, int n);
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 trun-
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
OK The function completed successfully.
ERR An error occurred in the function.
