StorPortWriteRegisterBufferUlong routine

The StorPortWriteRegisterBufferUlong routine transfers a given number of ULONG values from a buffer to the HBA.

Syntax


STORPORT_API VOID StorPortWriteRegisterBufferUlong(
  _In_  PVOID HwDeviceExtension,
  _In_  PULONG Register,
  _In_  PULONG Buffer,
  _In_  ULONG Count
);

Parameters

HwDeviceExtension [in]

A pointer to the hardware device extension. This is a per HBA storage area that the port driver allocates and initializes on behalf of the miniport driver. Miniport drivers usually store HBA-specific information in this extension, such as the state of the HBA and the mapped access ranges for the HBA. This area is available to the miniport driver immediately after the miniport driver calls StorPortInitialize. The port driver frees this memory when it removes the device.

Register [in]

Pointer to the register. The given Register must be in a mapped memory space range that was returned by StorPortGetDeviceBase.

Buffer [in]

Pointer to a buffer containing the data to be written.

Count [in]

Specifies the number of ULONG values to be transferred to the HBA.

Return value

None
