Struct rustix::ioctl::NoArg

pub struct NoArg<Opcode> { /* private fields */ }

Implements an ioctl with no real arguments.

Implementations

impl<Opcode: CompileTimeOpcode> NoArg<Opcode>

pub unsafe fn new() -> Self

Create a new no-argument ioctl object.

Safety

• Opcode must provide a valid opcode.
