[][src]Function nix::sys::socket::recvmsg

pub fn recvmsg<'a>(
    fd: RawFd,
    iov: &[IoVec<&mut [u8]>],
    cmsg_buffer: Option<&'a mut Vec<u8>>,
    flags: MsgFlags
) -> Result<RecvMsg<'a>>

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.


  • 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.
