It is similar to the DevHelp_SetIRQ function but it sets a 32-bit interrupt handler. Thr Interrupt handler must return INTERRUPT_HANDLED or INTERRUPT_NOT_HANDLED.
Syntax
APIRET APIENTRY KernSetIRQ(uint32_t IRQlevel, KernIRQHandler pIRQhandler, uint32_t IRQflag, void *pContext);
Parameters
- IRQlevel
- Interrupt level
- KernIRQHandler
- Pointer to a interrupt handler to be set ( typedef uint32_t __cdecl (*KernIRQHandler)(void*);)
- IRQflag
- Interrupt sharing (0=not shared, 1=shared)
- pContext
- Pointer to “context”. This pointer will be passed to the handler when an interrupt occurs.
