asio mixer

Boost ASIO is a library for Asynchronous Network Communication. Among them, async_write is a common function. However, if it is not used correctly, unexpected potential bugs may occur. For example, the following code: for (int i=0; i The code is simple, that is, loop N times and send n buffer blocks. Our goal is to receive buffer1, buffer2 ,......, Buffer n. However, in fact, the above Code is faulty, and the server may receive completely disordered

IO Model The io_service object is the scheduler in the asio framework, and all asynchronous io events are distributed and processed through it (an io_service object must be input in the constructor of the io object ). Asio: io_service;Asio: ip: tcp: socket (io_service ); In the asio framework, the main io synchronizati

Boost::asio can perform synchronous or asynchronous operations on I/O objects such as sockets, it is necessary to understand Boost::asio, your programs, and the process of their interaction before using Boost::asio. As an example of a bootstrap, we think about what happens when a socket performs a connection operation, and we start with a synchronous example wher

To the users of Photoshop software to detailed analysis to share the Channel mixer palette of the use of the tutorial. Tutorial Sharing: First look at the effect: What is a channel mixer and how it works. This small adjustment, as its name suggests, is the image of the channel. Most of the time working on the RGB color space, the channel is red, green, and blue,

The use of channel Mixer principle of the tutorial on the internet everywhere, but really can make people understand almost no, write people are understand, but not correct expression, let a person see the fog, finally can give up. I have carefully pondered these days, and finally realize what it is all about, make a memo, right when their own study notes. So that the time is not enough, can be warm and know new.

Many friends say that they do not have the basis of painting, do not know how to draw a beautiful picture. The mixer Brush tool developed by Photoshop CS5 makes it easy for people who don't know how to paint to draw beautiful pictures. If it is an art professional friend use it, it is even more powerful. Mixer Brush Tool? When you first hear the name, you may not know what it is, so practice it. We found

Introduction to Channel Mixer: In the process of using a channel mixer, it is necessary to pay attention to the addition or subtraction of color information from this channel or other channels of the same image location. That is, the image color information of a channel in space can be computed by this channel and other channel color information. Output channel can be a source image of any channel, the sour

Create a socket and acceptor and no longer construct io_service by yourself. Because the objects in ASIO need to save the reference of io_service, To manually constr

The Channel Mixer command may be the least common command in all palette commands in PS, because it is complex, intuitive, and involves a lot of theoretical knowledge, which is daunting to many beginners. However, once you can master it skillfully, you can get through the joints between color, channel, mask and so on to deepen the understanding and application of PS.

Comparison of socket programming between ACE and ASIO Transferred from: Free my soul Ace is a very mature middleware product. It is an adaptive communication environment, but it is too ambitious. There are a bunch of design patterns, and the architecture is layer after layer. It is a little difficult for beginners.ASIO is a basic asynchronous Io library developed by boost. It encapsulates socket and simplifies development based on socket programs. Th

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 the key points to solve the problem? Through these several days of in-depth understanding, I will summarize them: Aio is the asynchronous IO implemented by the kernel after linux2.6, or it is the true asynch
