Function sendmmsg

Source 
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,
Expand description

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.
