ncurses_doupdate -- Write all prepared refreshes to terminal
bool ncurses_doupdate ( void )
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.
