# simpleWriter

A method for processing an address space write request

## Declaration

```occ
static UInt32 simpleWriter( 
 void *refcon, 
 UInt16nodeID, 
 IOFWSpeed& speed, 
 FWAddressaddr, 
 UInt32len, 
 const void *buf, 
 IOFWRequestRefConreqrefcon); 
```

## Parameters

- `refcon`: Client's callback object.
- `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'.
- `reqrefcon`: Can be queried for extra info about the request.

## Return Value

Return Value UIn32 returns kFWResponseComplete on success
