Subject: [RFC PATCH for-next 1/4] epoll: struct epoll userspace definiton
Date: Sun, 23 Feb 2014 17:42:39 -0800 [thread overview]
Message-ID: <1393206162-18151-2-git-send-email-n1ght.4nd.d4y@gmail.com> (raw)
In-Reply-To: <1393206162-18151-1-git-send-email-n1ght.4nd.d4y@gmail.com>
In order to facilitate the addition, modification, and/or deletion
of multiple eventpoll entries in a single system call, struct epoll
is defined to communicate the same information as struct epoll_event
plus the associated file descriptor. The new epoll() system call uses
it for both input and output.
