srcl, wscrl, scrol 

The srcl set of routines is used to scroll a window.

Syntax 

     #include <curses.h>

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

     int scroll (WINDOW *win);

Parameters 

win                   A pointer to the window in which to scroll.

n                     The number and direction of lines to scroll.

Return Values 

OK                    Successful completion.

ERR                   An error occurred.

Description 

The scroll() routine scrolls the window win up one line.  The current
cursor position is not changed.

The scrl() and wscrl() routines scroll the window stdscr or win up or
down n lines, where n is a positive or negative integer, respectively.

The scrollok() routine must be enabled for these routines to work.


NOTE  The scroll() and scrl() routines are macros.


Implementation Considerations 

The scroll() routine is identical to XPG/3.  The wscrl() and scrl()
routines are UNIX System V implementations.

wscrl() and scrl() routines conform to UNIX System V.
