[−][src]Enum nix::sys::socket::ControlMessage

[−]
pub enum ControlMessage<'a> {
    ScmRights(&'a [RawFd]),
}
[−]

A type-safe zero-copy wrapper around a single control message, as used wih sendmsg. More types may be added to this enum; do not exhaustively pattern-match it.

ScmRights(&'a [RawFd])
[−]

A message of type SCM_RIGHTS, containing an array of file descriptors passed between processes.

See the description in the "Ancillary messages" section of the unix(7) man page.

Using multiple ScmRights messages for a single sendmsg call isn't recommended since it causes platform-dependent behaviour: It might swallow all but the first ScmRights message or fail with EINVAL. Instead, you can put all fds to be passed into a single ScmRights message.
