Struct IntegerSetter

pub struct IntegerSetter<const OPCODE: Opcode> { /* private fields */ }

Implements an ioctl that passes an integer into the ioctl.

To compute a value for the OPCODE argument, see the functions in the opcode module.

Implementations

impl<const OPCODE: Opcode> IntegerSetter<OPCODE>

pub const unsafe fn new_usize(value: usize) -> Self

Create a new integer Ioctl helper containing a usize.

Safety

• OPCODE must provide a valid opcode.
• For this opcode, it must expect an integer.
• The integer is in the valid range for this opcode.

pub const unsafe fn new_pointer(value: *mut c_void) -> Self

Create a new integer Ioctl helper containing a *mut c_void.

Safety

• OPCODE must provide a valid opcode.
• For this opcode, it must expect an integer.
• The integer is in the valid range for this opcode.

Trait Implementations

impl<const OPCODE: Opcode> Ioctl for IntegerSetter<OPCODE>

const IS_MUTATING: bool = false

Does the ioctl mutate any data in the userspace?

type Output = ()

The type of the output data.

fn opcode(&self) -> Opcode

Get the opcode used by this ioctl command.

fn as_ptr(&mut self) -> *mut c_void

Get a pointer to the data to be passed to the ioctl command.

unsafe fn output_from_ptr( _out: IoctlOutput, _extract_output: *mut c_void, ) -> Result<Self::Output>

Cast the output data to the correct type.
