This function deregisters an ISR with a specific hardware interrupt.
BOOL UnhookInterrupt( INT hwInterruptNumber, FARPROC pfnHandler );
Parameters
- hwInterruptNumber
[in] Hardware interrupt line. Note that this value indicates the actual hardware IRQ value and not the logical interrupt identifier. - pfnHandler
[in] Pointer to the ISR that is to handle interrupts for the specified IRQ.
Return Values
TRUE indicates success; FALSE indicates failure.
Remarks
This function removes the pfnHandler pointer from the location in a kernel table indicated by hwInterruptNumber and, instead, installs a dummy handler at this location.
