* Synopsis:
* int clearok(WINDOW *win, bool bf);
* int idlok(WINDOW *win, bool bf);
* void idcok(WINDOW *win, bool bf);
* void immedok(WINDOW *win, bool bf);
* int leaveok(WINDOW *win, bool bf);
* int setscrreg(int top, int bot);
* int wsetscrreg(WINDOW *win, int top, int bot);
* int scrollok(WINDOW *win, bool bf);
*
* int raw_output(bool bf);
*
* Description:
* With clearok(), if bf is true, the next call to wrefresh() with
* this window will clear the screen completely and redraw the
* entire screen.
*
* immedok(), called with a second argument of true, causes an
* automatic wrefresh() every time a change is made to the
* specified window.
*
* Normally, the hardware cursor is left at the location of the
* window being refreshed. leaveok() allows the cursor to be
* left wherever the update happens to leave it. It's useful
* for applications where the cursor is not used, since it reduces
* the need for cursor motions. If possible, the cursor is made
* invisible when this option is enabled.
*
* wsetscrreg() sets a scrolling region in a window; "top" and
* "bot" are the line numbers for the top and bottom margins. If
* this option and scrollok() are enabled, any attempt to move off
* the bottom margin will cause all lines in the scrolling region
* to scroll up one line. setscrreg() is the stdscr version.
*
* idlok() and idcok() do nothing in PDCurses, but are provided for
* compatibility with other curses implementations.
*
* raw_output() enables the output of raw characters using the
* standard *add* and *ins* curses functions (that is, it disables
* translation of control characters).
*
* Return Value:
* All functions return OK on success and ERR on error.
*
* Portability X/Open BSD SYS V
