[−][src]Struct nix::sys::socket::CmsgSpace

#[repr(C)]
pub struct CmsgSpace<T> { /* fields omitted */ }

A structure used to make room in a cmsghdr passed to recvmsg. The size and alignment match that of a cmsghdr followed by a T, but the fields are not accessible, as the actual types will change on a call to recvmsg.

To make room for multiple messages, nest the type parameter with tuples:

use std::os::unix::io::RawFd;
use nix::sys::socket::CmsgSpace;
let cmsg: CmsgSpace<([RawFd; 3], CmsgSpace<[RawFd; 2]>)> = CmsgSpace::new();

Methods

impl<T> CmsgSpace<T>[src]

pub fn new() -> Self[src]

Deprecated since 0.14.0:

Use the cmsg_space! macro instead

Create a CmsgSpace. The structure is used only for space, so the fields are uninitialized.
