# [−][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.

## Search Tricks

Prefix searches with a type followed by a colon (e.g., `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g., `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g., `str,u8` or `String,struct:Vec,test`)
