Expand description

A reply to an ioctl method call.

Variants§

§

Retry

Fields

§input: Vec<IoctlIovec>

Data that should be read by the kernel module and sent to the server when the ioctl is retried.

§output: Vec<IoctlIovec>

Buffer space that should be prepared so that the server can send back the response to the ioctl.

Indicates that the ioctl should be retried. This is only a valid reply when the flags field of the ioctl request contains IoctlFlags::UNRESTRICTED. The kernel will read in data and prepare output buffers as specified in the input and output fields before re-sending the ioctl message.

§

Done(Result<Vec<u8>>)

Indicates that the ioctl was processed.
