Synopsis

APTR AddVBlankInt(
         APTR intRoutine,
         APTR intData );

Function

Add a callback function that should be executed every vertical blank.
If your program can exit without rebooting the machine, RemVBlankInt()
has to be called prior to exiting.
    Only one interrupt routine may be added; always check the return
value of this function in case some other program already has used this
function.

Inputs

intRoutine  --  the callback function to invoke each vertical blank
intData     --  data passed to the callback function

Result

A handle used to manipulate the interrupt or NULL if the call failed.

Function

Remove a vertical blank interrupt routine previously added by a call to
AddVBlankInt().

Inputs

intHandle  --  return value from AddVBlankInt(); may be NULL in which case
               this function is a no-op.
