StorPortWriteRegisterBufferUchar routine

The StorPortWriteRegisterBufferUchar routine transfers a given number of unsigned bytes from a buffer to the HBA.

Syntax


VOID StorPortWriteRegisterBufferUchar(
  IN PVOID HwDeviceExtension,
  IN PUCHAR Register,
  IN ULONG Count
);

Parameters

HwDeviceExtension

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

Pointer to a buffer containing the data to be written.

Count

Specifies the number of bytes to be transferred to the HBA.

Return value

None

Requirements

Header

Storport.h (include Storport.h)

Library

Storport.lib
