clear and erase

SYNOPSIS

   #include <ocurses.h>
   

   int clear()
   int erase()

• Both routines change stdscr to all blanks.

• clear assumes that the screen may have garbage that it does not know about; this routine first calls erase and then clearok which clears the physical screen completely on the next call to refresh for stdscr. See the low-level ETI or curses(3ocurses) manual pages for more information about clearok.

• initscr automatically calls clear.

• In ETI UNIX System V Release 3.1 and later releases, clear and erase always return COK.

• Both routines are macros.
