scrollok 

The scrollok routine is used to enable scrolling of the screen.

Syntax 

     #include <curses.h>

     int scrollok (WINDOW *win, bool bf);

Parameters 

bf                    A Boolean expression.

win                   A pointer to the window in which to enable
                      scrolling.

Return Values 

OK                    Successful completion.

ERR                   An error occurred.

Description 

The scrollok() routine controls what happens when the cursor advances
outside the bottom boundary of a window or scrolling region.  When
enabled, if the cursor advances outside the bottom boundary of a window
or scrolling region, a call to wscrl() scrolls up one line and updates
the screen.  If scrollok() is disabled, a call to the wscrl() routine
leaves the cursor on the bottom of the line.

The terminal screen produces a scrolling effect if idlok() is also
enabled.

Implementation Considerations 

Identical to XPG/3
