Increase your abilities with functional examples for C++ community programming

Overview
• increase your C++ community programming utilizing Boost.Asio
• notice how Boost.Asio handles synchronous and asynchronous programming models.
• useful examples of client/server applications.
• take care of threading while writing community applications.
• Harness the facility of advance with lots of examples that you should construct upon.

In Detail

Network programming isn't really new and it's no mystery that it's now not a simple job. Boost.Asio offers an exceptional point of abstraction, with the intention that with a minimum volume of coding you could create appealing client/server purposes, and feature enjoyable within the process!.

"Boost.Asio C++ community Programming" exhibits the best way to construct client/server functions utilizing a library that's a part of the preferred peer-reviewed develop C++ Libraries. It analyzes even if you need to cross synchronous or asynchronous and the function that threading performs, when offering examples you could run and expand for yourself.

After overlaying the basics of Boost.Asio you'll become aware of how one can construct synchronous and asynchronous consumers and servers. additionally, you will see how one can have your individual asynchronous capabilities play great with Boost.Asio. As an advantage, we'll introduce co-routines, which make asynchronous programming a bit of cake. these days, community programming is a needs to, it doesn't matter what form of programmer you're. "Boost.Asio C++ community Programming" exhibits simply how uncomplicated networking could be, if you’re utilizing the appropriate tools.

What you are going to examine from this book
• find out how to simply reference Boost.Asio programming.
• Synchronous as opposed to asynchronous utilizing Boost.Asio.
• How threading impacts programming utilizing Boost.Asio.
• Create your personal echo consumer and server.
• extra examples of client/server purposes, either synchronous and asynchronous.
• enforce your individual asynchronous operations.
• Co-routines: asynchronous operations with a synchronous feel.
• Use Boost.Asio for SSL Networking.
• Debug Boost.Asio.
• Use Boost.Asio for greater than simply networking.

Approach

What you will have is a simple point of abstraction, that's simply what this publication offers at the side of Boost.Asio. Switching to Boost.Asio is simply a number of additional #include directives away, with assistance from this sensible and interesting guide.

Who this booklet is written for

This publication is excellent for builders that have to do community programming, who don't are looking to delve into the complex problems with a uncooked networking API. try to be conversant in middle enhance techniques, similar to shrewdpermanent tips and shared_from_this, source periods (noncopyable), functors and boost::bind, advance mutexes, and the increase date/time library. Readers must also be conversant in "blocking" as opposed to "non-blocking" operations.

So much of Microsoft's education kits are pretty well an analogous thing:while they are not a "one-book cease" for the MCSE candidate, they arewell-written introductions to the elemental recommendations. This strategyworked good numerous years in the past, while the MCSEs first got here out. regrettably, Microsoft has been ramping up the complexity of itstests progressively, and the home windows 2000 exams are geared toward professionalswho have not less than 12 months of networking W2K below their belts - whichmeans that straightforward concept-based education tools simply will not minimize itanymore.

Softwareentwicklung in C

Dieses Buch bietet sowohl eine anwendungsorientierte Einführung in die Programmiersprache C als auch eine moderne, strukturierte Herangehensweise an die Softwareentwicklung. Zahlreiche Beispiele werden zur Erläuterung angeführt, und der Weg von der Idee bis zur fertigen software program wird detailgenau mit allen Designentscheidungen erklärt.

Extra info for Boost.Asio C++ Network Programming

Example text

Async_write(stream, buffer [, completion], handler): This function asynchronously writes to a stream. The meaning of the arguments is similar to async_read. • read(stream, buffer [, completion]): This function synchronously reads from a stream. The meaning of the arguments is similar to async_read. • write(stream, buffer [, completion]): This function synchronously writes to a stream. The meaning of the arguments is similar to async_read: °° async_read(stream, stream_buffer [, completion], handler) °° async_write(strean, stream_buffer [, completion], handler) °° write(stream, stream_buffer [, completion]) °° read(stream, stream_buffer [, completion]) First, note that instead of socket, the first argument is a stream.

One more thing to note is that on_read() will constantly prepare for the next asynchronous read operation (see the last line of code). Asynchronous run(), run_one(), poll(), poll_ one() To implement the listening loop, io_service class provides four functions, such as run(), run_one(), poll(), and poll_one(). run(). You'll learn here what the other functions accomplish. Running forever Once again, run() will run as long as there are pending operations to be executed or you manually call io_service::stop().

Streambuf buf; async_read_until(sock, buf, match_punct, on_read); If we wanted to read up to space, we'd modify the last line to: async_read_until(sock, buff, ' ', on_read); The *_at functions These functions do random read/write operations on a stream. You specify where the read or write operation is to start from (the offset): • async_read_at(stream, offset, buffer [, completion], handler): This function starts an asynchronous read operation starting at offset, on the given stream. When the operation completes, it will call the handler.
