[−][src]Struct nix::sys::socket::CmsgSpace
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();
