Function nix::sys::socket::recvmsg

pub fn recvmsg<'a, 'outer, 'inner, S>(
    fd: RawFd,
    iov: &'outer mut [IoSliceMut<'inner>],
    cmsg_buffer: Option<&'a mut Vec<u8>>,
    flags: MsgFlags
) -> Result<RecvMsg<'a, 'inner, S>>
where
    S: SockaddrLike + 'a,
    'inner: 'outer,

Receive message in scatter-gather vectors from a socket, and optionally receive ancillary data into the provided buffer. If no ancillary data is desired, use () as the type parameter.

Arguments

• fd: Socket file descriptor
• iov: Scatter-gather list of buffers to receive the message
• cmsg_buffer: Space to receive ancillary data. Should be created by cmsg_space!
• flags: Optional flags passed directly to the operating system.
