# fSenseBufferAddr

The virtual address of the buffer that the dext creates to transfer sense data.

```
uint64_t fSenseBufferAddr;
```

## Discussion

The framework uses this address to create an <doc://com.apple.documentation/documentation/DriverKit/IOMemoryDescriptor> in the kernel that [`fSenseLengthRequested`](/documentation/SCSIPeripheralsDriverKit/SCSIDeviceOutParameters/fSenseLengthRequested) specifies and maps to the dext process.
