This function masks hardware interrupts. This function can be called from kernel-mode drivers and user-mode drivers.

VOID InterruptMask(
  DWORD idInt,
  BOOL fDisable
);

Parameters

  • idInt
    [in] Interrupt identifier to be associated with the interrupt service thread (IST).
  • fDisable
    [in] Flag to disable (mask) or enable (unmask) the interrupt.

Return Value

None.

Remarks

A device driver calls InterruptMask to temporarily mask or unmask an interrupt so that the device driver can safely access the hardware without being interrupted by the same interrupt.
