Function nix::sys::socket::sendmmsg

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