DESCRIPTION

38       The erase() and werase() routines copy blanks to every position in  the
39       window.
40
41
42       The  clear()  and  wclear() routines are like erase() and werase(), but
43       they also call clearok() , so that the screen is cleared completely  on
44       the next call to wrefresh() for that window and repainted from scratch.
45
46
47       The  clrtobot() and wclrtobot() routines erase all lines below the cur‐
48       sor in the window. Also, the current line to the right of  the  cursor,
49       inclusive, is erased.
50
51
52       The  clrtoeol()  and wclrtoeol() routines erase the current line to the
53       right of the cursor, inclusive.
54

RETURN VALUES

56       All routines return the integer OK, or a non-negative integer if  imme‐
57       dok() is set. See curs_outopts(3CURSES).
