392 class IODBDMAMemoryCursor : public IOMemoryCursor
438 @discussion Generates a list of DBDMA descriptors where the address and length fields are filled in appropriately. But the client is expected to fill in the rest of the DBDMA descriptor as is appropriate for their particular hardware. Wraps IOMemoryCursor::genPhysicalSegments.
