FwRpcResponse

kernel::fwctl

Enum FwRpcResponse 

Source 
pub enum FwRpcResponse {
    InPlace(usize),
    NewBuffer(KVVec<u8>),
}
Expand description

Response from a Operations::fw_rpc call.

Variants§

§

InPlace(usize)

Reuse the input buffer as the output, with the given output length.

The callback returns EINVAL if the output length exceeds the input buffer length.

§

NewBuffer(KVVec<u8>)

Return a newly allocated buffer as the output.
