### 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 wgetscrreg(const WINDOW *win, int *top, int *bot);
int scrollok(WINDOW *win, bool bf);
int raw_output(bool bf);
bool is_cleared(const WINDOW *win);
bool is_idlok(const WINDOW *win);
bool is_idcok(const WINDOW *win);
bool is_immedok(const WINDOW *win);
bool is_leaveok(const WINDOW *win);
bool is_scrollok(const WINDOW *win);
### 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.
wgetscrreg() gets the top and bottom margins as set in wsetscrreg().
idlok(), idcok(), is_idlok() and is_idcok() do nothing in PDCursesMod,
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).
is_cleared() reports whether the specified window causes clear at next
refresh.
is_immedok() reports whether the specified window is in immedok mode.
is_leaveok() reports whether the specified window is in leaveok mode.
is_scrollok() reports whether the specified window allows scrolling.
### Return Value
All functions returning integers return OK on success and ERR on
error.
is_cleared(), is_immedok(), is_leaveok() and is_scrollok() are
booleans and return TRUE or FALSE.
is_idlok() and is_idcok() are provided for compatibility with other
curses implementations. They have no real meaning in PDCursesMod and
will always return FALSE.
