This function is called by an OEM from the OAL ISR routine. This function determines which chained, or shared, interrupt device triggered an IRQ event.
Syntax
DWORD NKCallIntChain(
BYTE irq
);
Parameters
- irq
[in] Identifies the IRQ value.
Return Value
If no ISR has handled the IRQ event, SYSINTR_CHAIN is returned.
Otherwise, a valid SYSINTR value is returned to the OEM. The OEM must then pass this value back to the kernel so the IST can be triggered.
Remarks
The OEM has full control of the IRQ values that can be chained and those that cannot. When this function is called, all work required to enable C-language code in an installed ISR is performed.
