PHW_INTERRUPT routine

The PHW_INTERRUPT routine prototype declares the miniport driver's interrupt handler routine.

Syntax


typedef BOOLEAN (*PHW_INTERRUPT)(
  _In_ PVOID DeviceExtension 
);

Parameters

DeviceExtension [in]

Pointer to the miniport driver's per-HBA storage area.

Return value

If the interrupt handler routine determines that its HBA generated the interrupt, it returns TRUE. If the interrupt handler determines that its HBA did not generate the interrupt, it should return FALSE as soon as possible.

Remarks

The interrupt handler routine for both SCSI and StorPort miniport drivers are declared using this prototype.

For more information about the SCSI miniport driver's interrupt handler routine see HwScsiInterrupt.

For more information about the miniport driver's interrupt handler routine that is used with the StorPort driver see HwStorInterrupt.

Requirements

Target platform

Header

Srb.h (include Storport.h, Srb.h, or Storport.h)
