clrtobot, wclrtobot - clear to end of screen
The routine begins at the current cursor position in the default window and changes the remainder of the screen to blanks. The current cur-
sor position is also changed to a blank.
The routine begins at the current cursor position in the specified window and changes the rest of the screen to blanks, including the cur-
rent cursor position.
The routine is a macro.
The and functions return OK on success and ERR on error.

erase, werase, clear, wclear, clrtobot, wclrtobot, clrtoeol, wclrtoeol - clear all or part of a curses window
# include <curses.h>
int werase(WINDOW *win);
int wclear(WINDOW *win);
int wclrtobot(WINDOW *win);
int wclrtoeol(WINDOW *win);
The erase and werase routines copy blanks to every position in the window, clearing the screen.
The clear and wclear routines are like erase and werase, but they also call clearok, so that the screen is cleared completely on the next
call to wrefresh for that window and repainted from scratch.
The clrtobot and wclrtobot routines erase from the cursor to the end of screen. That is, they erase all lines below the cursor in the win-
dow. Also, the current line to the right of the cursor, inclusive, is erased.
The clrtoeol and wclrtoeol routines erase the current line to the right of the cursor, inclusive, to the end of the current line.
Blanks created by erasure have the current background rendition (as set by wbkgdset) merged into them.
All routines return the integer OK. The SVr4.0 manual says "or a non-negative integer if immedok is set", but this appears to be an error.
Note that erase, werase, clear, wclear, clrtobot, and clrtoeol may be macros.
These functions are described in the XSI Curses standard, Issue 4. The standard specifies that they return ERR on failure, but specifies
no error conditions.
Some historic curses implementations had, as an undocumented feature, the ability to do the equivalent of clearok(..., 1) by saying touch-
win(stdscr) or clear(stdscr). This will not work under ncurses.
