# doWrite

An abstract method for processing an address space write request

## Declaration

```occ
virtual UInt32 doWrite(
 UInt16nodeID,
 IOFWSpeed &speed,
 FWAddressaddr,
 UInt32len, 
 const void *buf,
 IOFWRequestRefConrefcon) = 0; 
```

## Parameters

- `nodeID`: FireWire Write to nodeID.
- `speed`: at this 'speed'.
- `addr`: with FireWire address 'addr'.
- `len`: write 'len' bytes to nodeID.
- `buf`: obtain bytes from location given by 'buf'.
- `refcon`: Can be queried for extra info about the request.

## Return Value

Return Value UIn32 returns kFWResponseComplete on success
