typedef UInt32 (*FWWriteCallback)(void *refcon, UInt16 nodeID, IOFWSpeed & speed, FWAddress addr, UInt32 len, const void *buf, IOFWRequestRefCon requestRefcon);

Parameters

  • device:

    is the node originating the request

  • speed:

    is the FireWire speed of the request, update it if you need to control the speed of the reply, otherwise the response will be the same speed.

  • addr:

    is the address the device is requesting to write to

  • len:

    is the number of bytes to write

  • buf:
