Re: about the tcp_sendpage()

["R.wen" <rwen2012@xxxxxxxxx>]

Thanks for your reply, I do know that, there is a inet_stream_ops
structure there, and also the function sock_sendpage() here as follow. 

But is there a system call that use it? Or how does the user-application use this function?

Thanks.
    
/*********************************************************/

static ssize_t sock_sendpage(struct file *file, struct page *page,
                 int offset, size_t size, loff_t *ppos, int more)
{
    struct socket *sock;
    int flags;

    sock = file->private_data;

    flags = !(file->f_flags & O_NONBLOCK) ? 0 : MSG_DONTWAIT;
    if (more)
        flags |= MSG_MORE;

    return sock->ops->sendpage(sock, page, offset, size, flags);
}
