### Class

# FwupdPlugin CfuOffer

#### Description [src]

    class FwupdPlugin.CfuOffer : FwupdPlugin.Firmware
    {
      /* No available fields */
    }

A CFU offer. This is a 16 byte blob which contains enough data for the device to either accept or refuse a firmware payload. The offer may be loaded from disk, network, or even constructed manually. There is much left to how the specific firmware implements CFU, and it’s expected that multiple different plugins will use this offer in different ways.
