/* Name: outopts
 *
 * 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.
 *
