clear(3X)                                                         clear(3X)

NAME
     clear, erase, wclear, werase - clear a window

SYNOPSIS
     cc [flag ...] file ... -lcurses [library ...]

     #include <curses.h>

     int clear(void);

     int erase(void);

     int wclear(WINDOW *win);

     int werase(WINDOW *win);

DESCRIPTION
     The clear(), erase(), wclear() and werase() functions clear every
     position in the current or specified window.

     The clear() and wclear() functions also achieve the same effect as
     calling clearok(), so that the window is cleared completely on the
     next call to wrefresh() for the window and is redrawn in its entirety.

RETURN VALUE
     Upon successful completion, these functions return OK. Otherwise, they
     return ERR.

ERRORS
     No errors are defined.

SEE ALSO
     clearok(3X), curses(3X), doupdate(3X), curses(5).
