Function Documentation

getKeyboardAutoRepeatRate()

static int getKeyboardAutoRepeatRate ( )

static

Used when acceleration is turned on.

Warning

This function is not part of the public interface.

We need to get the keyboard auto repeat rate from OS. This value is used as argument when starting acceleration related timers.

Every platform should, either, use native calls to obtain the value or hard code some reasonable rate.

Remember that time value should be given in msecs.
