Struct kernel::file::IoctlCommand

pub struct IoctlCommand { /* private fields */ }

Represents an ioctl command.

It can use the components of an ioctl command to dispatch ioctls using IoctlCommand::dispatch.

Implementations

impl IoctlCommand

pub fn dispatch<T: IoctlHandler>(
    &mut self,
    handler: T::Target<'_>,
    file: &File
) -> Result<i32>

Dispatches the given ioctl to the appropriate handler based on the value of the command. It also creates a UserSlicePtr, UserSlicePtrReader, or UserSlicePtrWriter depending on the direction of the buffer of the command.

It is meant to be used in implementations of Operations::ioctl and Operations::compat_ioctl.

pub fn raw(&self) -> (u32, usize)

Returns the raw 32-bit value of the command and the ptr-sized argument.
