name of this function, and anything else documented about this
function may change without notice in a future release of PHP.

ncurses_cbreak() disables line buffering and
character processing (interrupt and flow control characters are
unaffected), making characters typed by the user immediately
available to the program.
ncurses_cbreak() returns TRUE or NCURSES_ERR
if any error occurred.
