Abstract base class for all interrupt events.
Size: 0x4 bytes
| Offset | Type | Description |

| 0x0 | void ** | Pointer to vtable |
This abstract base class defines virtual KSchedulableInterruptEvent* handleInterruptAndGetKSchedulableInterruptEvent(u32 interruptID) = 0. It's actually the function called by the IRQ handler, which returns a KSchedulableInterruptEvent to call the second virtual method of (which signals the object) after a reschedule.
If either NULL or 1 is returned, nothing will be signaled. If NULL is returned, no post-interrupt rescheduling will be done.
The kernel uses the KEventInterruptEvent field of a KEvent when binding public interrupts per svcBindInterrupt request.
