AtaPortReadPortBufferUlong function (irb.h)

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

Note  The ATA port driver and ATA miniport driver models may be altered or unavailable in the future. Instead, we recommend using the Storport driver and Storport miniport driver models.
