pub fn recvmsg<'a, S>(
    fd: i32, 
    iov: &'outer mut [IoSliceMut<'inner>], 
    cmsg_buffer: Option<&'a mut Vec<u8, Global>>, 
    flags: MsgFlags
) -> Result<RecvMsg<'a, S>, Errno> where
    S: 'a + SockaddrLike, 

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.
