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.
