Function nix::sys::socket::sendmmsg[−][src]

pub fn sendmmsg<'a, I, C>(
    fd: RawFd, 
    data: impl IntoIterator<Item = &'a SendMmsgData<'a, I, C>>, 
    flags: MsgFlags
) -> Result<Vec<usize>> where
    I: AsRef<[IoVec<&'a [u8]>]> + 'a,
    C: AsRef<[ControlMessage<'a>]> + 'a, 

An extension of sendmsg that allows the caller to transmit multiple messages on a socket using a single system call. This has performance benefits for some applications.

Allocations are performed for cmsgs and to build msghdr buffer

Arguments

  • fd: Socket file descriptor
  • data: Struct that implements IntoIterator with SendMmsgData items
  • flags: Optional flags passed directly to the operating system.

Returns

Vec with numbers of sent bytes on each sent message.
