AtaPortCopyMemory function

Description

The AtaPortCopyMemory routine copies data from one location to another.

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.

Parameters

`WriteBuffer` [out]

A pointer to the destination buffer.

`ReadBuffer` [in]

A pointer to the source buffer.

`Length` [in]

Specifies the number of bytes to transfer from ReadBuffer to WriteBuffer.

Remarks

The miniport driver calls the AtaPortCopyMemory routine to copy data from one system-allocated area to another.
