   (PHP 4 >= 4.1.0)
   ncurses_doupdate -- Write all prepared refreshes to terminal

Description

   bool ncurses_doupdate ( void )

   Warning

   This function is EXPERIMENTAL. The behaviour of this function, the
   name of this function, and anything else documented about this
   function may change without notice in a future release of PHP. Use
   this function at your own risk.

   ncurses_doupdate()() compares the virtual screen to the physical
   screen and updates the physical screen. This way is more effective
   than using multiple refresh calls. Returns TRUE on success or FALSE on
   failure.
