OSInitBetweenKeyDelay |
Function (ROM Call 0x249*) |
Sets the rate at which a key autorepeats.
OSInitBetweenKeyDelay sets the rate at which a key autorepeats to rate
(note that only few keys have an autorepeat feature, namely arrow keys and backspace).
The measuring unit for this function is 1/395 s (because
Auto-Int 1 is triggered 395 times per second), and the default value for
rate is 48. OSInitBetweenKeyDelay returns the previous autorepeat rate.
Greg Dietsche pointed out that on HW2 (precisely, if the gateArray
field of the structure returned by
FL_getHardwareParmBlock
exists and is 2 or higher), TIOS immediately multiplies the value passed to
it by 3/4.
This is probably a bug, as this implies that there is no way to restore the
rate to the value previously returned by OSInitBetweenKeyDelay. To work
around this problem, OSInitBetweenKeyDelay is defined as a macro which
detects this modification in a smart way, and tries to revert it for the
return value.
