The signal binding mechanism simply means that the external signal is converted to an internal IO event for processing. Since the signal capture function is globally bound, there is no way to bind the IO event and file descriptor as an IO event, and
Libevent Listener event has the following file descriptors/sockets, no timeout length signal file descriptor/socket, set timeout length
For time, the Libevent internal time management is implemented through the smallest heap, for the following
Write a very simple time server as an example: when you connect up, the Server side provides you with a direct timeframe and then ends the connection. Event_init () represents the variable used by the initialization libevent. Event_set (&ev, S,
Libevent's original intention is to design a cross-platform lightweight i/0 framework, because of historical problems, I/O multiplexing mechanism of each platform is difficult to unify. Therefore, this part of the process of cross-platform approach
In Libevent, a convection pipe, or full-duplex pipe, is established by using Socketpair to unify the signal event with the handle event.
First look at the data structure:
struct evsignal_info { struct event ev_signal; /// int ev_signal_pair[2];
In testing one of our developed APK (using Libevent-2.1.3-alpha as the network library) when found a strange problem, domain name resolution has the Times wrong non-recoverable name resolution failure. In the company occasionally error, then the
PHP uses pcntl and libevent to implement the Timer function. PHP uses pcntl and libevent to implement the Timer function. let's take a look at the example. the pcntl (PHP thread) is explained below. Copy the code as follows :? PhpfunctionnewChild ($
Libevent cross-platform network library. The event network library based on the Reader model provides a convenient callback and event mechanism. Its latest stable version 2.0.10-stable is added to windows iocp, which makes windows more powerful
Use libevent to write Linux Services (2)
4. process connectionsSo far, you have completed event settings, added events, and entered an event loop. But what should I do when an event occurs (connection is established here? Smart users will
In the reactor mode of the previous blog post libevent, we know that an important component of the reactor pattern is the event multicast mechanism (the events demultiplexer). In Libevent, support for the event multiplexing mechanism relies on the
There was a previous article that described some contrasts:Http://www.cnblogs.com/charlesblc/p/6078029.htmlHere's a bit more about code and application.Look at the two sides of the HelloWorld basic understanding of the approximate.Libevent's Hello
I have been using libevent recently and found a small problem about libevent event registration:
For a server, it is very likely that the registration time type is continuous read and write; that is, ev_read | ev_persit (read), and then the
Event_add Append the event to the Ev_base in the current event, and the TV cannot be empty if it needs to be timedIntevent_add (struct event *ev, const struct Timeval *tv) {struct Event_base *base = ev->ev_base; Event_add will add the event to his
In Libevent, the implementation of the timer is achieved by a priority queue based on the minimum heap.
The two data structures are unfamiliar to the 6.5 section of the introduction of the algorithm can be flipped.
The main source code is in the

Event_base is the Libevent event-driven, and also the direct embodiment of reactor model. Any code that uses libevent needs to create a base at the very beginning, and then any interface functions are associated with the base, and the following is

Over the past few days, I have been working on a large volume of data solutions for linux. I have continuously learned about aio, epoll, libevent, boost: asio. In the past, I only knew that they are both asynchronous and non-blocking, but what are
