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

impl<const OPCODE: Opcode> IntegerSetter<OPCODE>
Sourcepub const unsafe fn new_usize(value: usize) -> Self
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.
Sourcepub const unsafe fn new_pointer(value: *mut c_void) -> Self
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.
